No, but Emily's 'death' was so incredibly cruel for Grace, and that's putting aside the obvious 'having to witness a small, innocent child she cares about being violently mangled beyond repair right before her eyes' thing. I did talk about the way both her and Leon reach a point of complete hopelessness in the story before, but I'm just gonna ramble about Grace alone here because I've got major Grace brainworms.
The first time she encounters Marie, she's a terrified mess, justifiably so!
She's shaking, gasping for air, hell, she's barely able to string two sentences together. Her only objective at this point is just to get the hell out of this place and hopefully avoid ever encountering something like that ever again. And she can handle herself pretty nicely, all things considered. Sure, she's no Claire who has no problem confronting her enemies head-on, and her gameplay is centered around careful strategizing and knowing when to use force, and when to hold back (even if you can go full bloodbath mode with her if you want). But for someone who's been thrust into the thick of it with zero prior experience, she can handle herself, however fearfully.
That said, that's what her survival strategy is based on: avoid confrontation whenever possible. That's what's keeping her safe, and that's what she's most concerned about in the moment. This begins to shift once she realizes she has to use Emily's help to finally get out for good, though. I think Grace was somewhat wary of Emily up until the moment she actually got to interact with her properly, like a small child she really is, not some dangerous specimen to be locked away behind a huge observation glass.
It's harder to be wary when you have this blind little girl clinging on to you, feeling scared and confused of all the scary noises she can't possibly understand, and depending on you to keep her safe until you get where you need to be.
On the one hand, Grace needs Emily to solve this puzzle and get the piece she can't by herself. On the other hand, Grace didn't really need to put herself out in the open and at very real risk by going back out to guard the room Emily is in. She could have remained inside the room, maybe barricaded the door and urged Emily to be quick about it. But no, instead she chooses to reassure Emily, swallow down the same fear that's been her main driving force up until now, and go back out there so Emily doesn't have to worry.
It's the first time she puts herself at a direct risk when it's not driven by her sense of guilt like I briefly talk about here. She does this simply so that Emily can feel safer and able to concentrate, not out of her own fear, or guilt, or any real concern for herself or her uncertainty in her own capabilities. She's shaky, she's still scared, but when she has someone depending on her to keep them safe and calm? She can put aside all the things that hold her back under normal circumstances and stand her ground, however shakily.
I do think Emily granting her that feeling of actually doing something right for once and helping out someone who needed her is a very important piece as to why Grace gets so attached to her so quickly. And her fear and guilt don't just disappear. When Marie quite literally bashes through the wall and grabs Emily, Grace is just as terrified and lost as she was hours ago, unable to do anything but watch.
She doesn't immediately throw herself into action to try and save Emily right then and there, nor does she get some heroic moment of badass resolve. She's momentarily lost on what to do, scared, confused, and overwhelmed.
Her fear and guilt are still there. Hell, her guilt is the first thing she feels once the immediate fear subsides: 'This is all my fault.' The first thing she does is still blame herself. But her guilt does drive her to act instead of giving up, to push forward and try to fix things before it's too late. She'll be putting herself at direct risk, but giving up right now would mean accepting that everything really is her fault, and that she can't do anything right. And despite all her nerves, she's not actually ready to accept that, especially not right after she did manage to successfully hold her own and keep Emily safe.
And I think what's especially sad about Emily's death, and Grace's overall response to it, and to Leon is that... Leon is the one that actually reassured her when she was already petrified over losing Emily.
When she was panicking and not knowing what to do after fighting so hard to get them both out of this nightmare safe, Leon is the one to put a metaphorical calming hand on her shoulder to pull her out of it and reassure her that they're going to be okay. He's the one who entrusts her to keep Emily safe by herself, too. He trusts her to handle herself.
And if someone clearly as experienced as he is feels sure enough in her capabilities to do that, then surely he must be right. He's the one that gave her Requiem before, when she was nothing but a stuttering, panicking mess. Looking past the fact that it comically only had a single bullet at the time, Requiem did symbolize Grace finding her inner resolve to keep going on her own and trusting herself to get through this.
So, of course Grace is so much more confident and determined than ever before once she reaches the water treatment facility.
It's such a sadistic irony, too, because she finally, finally believes in herself, fully. She believes that she can protect Emily, that she doesn't have to cover and hide anymore, that she can do something just by staying calm and focused. She managed so much up until this point, despite all the odds stacked against her. She's been reassured and given hope by a man she might not know well, but a man she knows is so much more experienced than she is. If he trusts her to keep Emily safe by herself, then surely she can do this.
But, the opposite happens. Not only does Emily die, but she doesn't even get to do so painlessly or quietly. Instead, Grace has to watch her writhe and scream and twist into something abhorrent, unable to do a single thing about it. She can't talk sense into her no matter how many times she tries.
She can't stop Leon from shooting at her when he arrives, because she doesn't have the strength needed to overpower him, despite her genuinely trying without stopping and clinging to his arm until the very last moment.
She can't do a single thing to fix this, despite her genuine efforts to do so. Sure, she finally defeated the Girl, but what's the point of it all? She did it so Emily would be safe from her. Not for herself. But she wasn't fast enough, or maybe she never could have done anything in the first place.
It's no wonder she reaches a point of giving up on herself completely, a point of choosing to not even try and do anything from then on. She got to this point by trying. By trying to fix her old mistakes, by trying to prove herself stronger than she thought she was, by trying to help someone she cares about. Look where that got her. All she did was make this poor little girl suffer a fate no child should have to experience. After all, maybe if she had just left her in that cell, she would've been safe and sound. Maybe if she never even tried to do anything, nobody would be hurt. Just like on that rainy night, if she hadn't tried to argue with her mom, to call the police, to figure out what's going on, to go back for their things, her mom could have been alive.
Maybe it really is all her fault, and the best thing she can do is just... never even try again.
No wonder she literally and metaphorically throws Leon's words back at him in the form of Requiem.
He's also the one who gave her that push to find her resolve. The same resolve that didn't even amount to anything for her. They're not going to be okay, because Emily is gone, and she didn't get Emily safe, because she failed.
So why should she listen to him now?
It's also why I wish Emily being alive was given a tad more narrative focus instead of a simple line in the end. It's such a pivotal culmination of everything Grace has been through up until that point, the payoff just doesn't land nearly as hard, and that really is a shame.
