Casualties include injured, don’t they?

They do, but equating it to “fatalities” is a pretty common mistake. Unfortunate.

everyone’s mouths looked like they were moving kinda weird during the action shots.

I didn’t notice that, but it may have been a playback issue.

As far as the character introductions go, there’s not much to them. Genesis seems like an arrogant tryhard. SAM seems like a…cheerful Data-type? Jay-Den just seems like a Klingon. Darem seems like…another tryhard, but less arrogant than Genesis.

Caleb’s is kind of odd, as it features very little Caleb. I guess he seems kind of cocky, but it’s hard to say.
