What stood out to me the most about Episode Aigis' first and second acts was how despite Makoto rarely being mentioned - and obviously never by name - you feel his presence hanging over every conversation. He is the true, underlying, unspoken topic of half of what the team talks about, long before the arguments and insults start flying.
You never see the funeral, you never see his grave. Instead, the game shows something so much worse: the hole Makoto has left in his friends by leaving the way he did. (spoilers under the cut)
Aigis naturally falling into Makoto's role as the silent protagonist leader-kun, and for the same reasons as him: introversion caused by deep self loathing.
Junpei proverbially tightening his belt and straightening his shirt, stepping up to be the team anchor because someone has to keep this team from falling apart on each other. How you see that through his jokes, how carefully timed they are to avoid a conversation going down a dark path. He's gone from the guy who blamed Makoto when things went wrong, to the one keeping the team's eye on the ball.
Akihiko doing his level best to stay strong, to prove to himself that he didn't fail his two best friends.
Yukari and Mitsuru's paralleled pain, both having been failed and left behind by yet another man in their life. And how that pain manifests differently - Mitsuru isolating herself for much of the expansion's first act, and Yukari's attempts to shut away the pain manifesting in petty jealousy over Aigis receiving the wild card powers.
Ken appearing to be totally fine until you sit back and realize that what you're seeing is a child's carefully trained numbness in response to trauma. He's lost his mom and two surrogate older brothers. He is, tragically, the best of the group at pretending he's okay.
The only one who seems to be adjusting as well as anyone can is Fuuka. You get the sense that she's the only one who is actually attending therapy for this. And even then, when the story gets to its end, it's clear that she's as hurt as the rest of them.
All of this is conveyed through dialogue way before the colosseum lays all the trauma bare. Genuinely masterful stuff.
the real reason that aigis hates ryoji is just because she's (rightfully) worried he's going to steal her mans and/or womans. this is correct information.
