Here's the order of who I think would react the worst to Brooklyn being alive reveal:
Kenji
Sammy
Yaz
Ben
Darius
Explaining my thought process and starting with Darius.
So, in the end his relief at her being alive will overpower any bad feelings he'll get. There's also the fact that even though he says he doesn't blame himself for her death doesn't mean he doesn't still feel guilt. I can see how finding out she's alive can bring lightness to all that guilt he has been carrying all these months.
Add to what could be a love corner (I refuse to call it a love triangle because neither Darius or Kenji looks to have or be developing romantic feelings for each other. And y'know completing the triangle) they could have Darius' reaction to Brooklyn being opposite of Kenji's. As they have shown many times before and so will again.
Next up! Ben~ It wouldn't surprise me that Mr. Conspiracy Theorist and always on Dark Jurassic wouldn't have a sticky note idea that maybe she's alive. That maybe she faked her own death to lose the people who are out to get them or maybe the bad people faked her death because they needed her. Death pending.
So it would soften the blow a bit. Also unlike the others it doesn't appear he manifested any negative feelings aimed at Brooklyn that wasn't grief. He definitely would be ticked off when discovering she used Dark Jurassic to communicate with others because "Hello! I know you know I'm always on there!" Which would cool off because he would get why she didn't. Couldn't.
Yaz~! She would definitely be peeved that Brooklyn faked her death to everyone she loves. Though she would take it more calmly while stewing in her anger and trying to understand her. Because Brooklyn was there when she needed someone to support her and not treat her gently. So she'll listen and not like it but at least she won't bite her head off for it (maybe just the hand *ba dum tss*).
Another reason for her anger though will be because of how much Brooklyn hurt Sammy. Yaz may not have been there physically to see how much she was hurting in her grief, but she will be when Sammy doesn't try to be nice about the reveal. Yaz will always be ready to fight for Sammy.
