Honestly Shadowheart doesent come across as a bad person to me. Distrusting, snarky and sarcastic maybe. But given the fact that she was just kidnapped by literall brain eating aliens who can also mind control people id say part of that distrust is justified.
Lae'zel though. Hoo boy. She was giving me lip when I was on my way to help her so I told her to say 'please'. And when she couldnt even managed that id figure id let her rot for a few minutes before coming back to see if she came around. And when I walked off screen got an update that basicly meant that I left her to her fate. Whoops.
D'oh well. Plenty of teammates left to fill a full team.
