Grace and Simon's friendship was the realest thing in the Apex, but they were never able to really help each other or be vulnerable with each other. I think this conversation in Jungle Car exemplifies that on Grace's end:
Simon: Threats seem minimal.
Grace, fake-serious: But Simon presence remains aloof and dorky!
Grace: Dude, we are the Apex, but also... we're Grace and Simon, remember!
Simon: Yeah...
Grace, mockingly: Yeah.
Grace: Yeah, what? I've seen you lead an army of kids, but I've also seen you play sockball! You can play super serious general guy when we get back. Until then, loooosen uuuup!
Grace: Think of it as us being on leave.
These are the things that really strike me about this conversation:
Grace is giving Simon a hard time, but she's also being truthful and sincere. I don't see any lies or even anything misleading here.
Grace calls his usual persona "play[ing] super serious general guy" but also gives him the "think of it as us being on leave" out. She's using the rhetorical technique of appealing to his personal values, without being dishonest and pretending she shares them.
Notice how indirect Grace is being about her emotional reasoning. We can infer that she really wants to relax and have fun with Simon, because that's clearly what she's trying to achieve here and what we see them doing together after this conversation. But Grace doesn't say "I miss you" or "wouldn't it be fun to hang out?" or anything like that. She says what she has to say to get what she wants, expressing as little of her interior self as possible.
Also interesting how she pivots to talking about just Simon and not both of them in the middle there (while talking about specifics?)... like, she doesn't say "we lead an army but we also goof around together", she says "I've seen you" etc. I wonder if that's also partly because Simon responds better to that kind of approach.
If this is also an attempt to help Simon calm down and feel better (and I think it is), then that's also something Grace isn't explicitly acknowledging. I don't think in this case it's "bad" not to flat out say that, but I do think it's part of a larger pattern of their relationship... like, she didn't need to say that here, but she didn't say that here because this generally isn't a friendship where they acknowledge each other's feelings or caring about each other's feelings, and in a lot of other situations... that's bad! (It's also not something Simon asked for, or that I think he understands he could ask for/knows how to ask for.)
Interesting implicit acknowledgement from Grace here that playing Apex leaders works against their ability to actually be themselves.
It's like, this is a conversation that I could imagine happening between two people who have a healthy relationship, but because this is (as far as I can tell) the most sincere and open and caring conversation they'd had in ages, and as sincere and open and caring as it ever gets between them until Grace opens up in the chalet episode... feels like symptoms of a broader pattern.
