I hate this scene for a number of reasons:
1. Why is Blitzo having a psychotic break? He's never been shown to suffer from psychosis before or after this scene. The closest thing is "Truth Seekers", but even then it's not the same
2. Everything we've seen of Blitzo and Loona's relationship paints the day he adopted her as one of the happiest days of his life. Why does he have PTSD? Did seeing Loona cry traumatize him
that much?
3. Why are they even there? Blitz smashed a hole in the window of the van. Just jump out when it starts moving, or when it's stopped at some lights or something. Yes, there are security guards, but you have a gun.
Fucking shoot them. Blitz has never worried about collateral damage before.
4. Even if Blitz didn't want to shoot his way out, I can't see Stolas not trying to sneak away instead of dicking around with Blitz. Because
Octavia is missing.
You're right. We got Loona's backstory, and that's great, but the writers had to really twist and bend the characters to make them fit the scene, even by this show's standards.
