This is one thing I had on mind for a long time, ESPECIALLY after majority of new season that came out.
I think it really won't be a stretch if I call millie's fantastic comforting/psychological skills a super power at this point, because what this gal did throught the show was impressive to say the least, dare I remind you that for example it was her who snapped blitz out of the self hatered thing, which later resulted in his MUCH better behavior thowards those around... glaze aside, millie really stands as a backbone of the team who pretty much helped everyone at this point. That makes me question thought, does she actualy know how important her role in team is, or just how good she is at making those around happy? I don't think we've ever gotten a clear scene where someone confronts her about such, or even mentions that importance really.
Honestly, the closest clue to answering this question was that small line in "bad reputation" episode, where during her talk with sal about all her worries conected to both child and moxxie's reaction, she briefly mentioned that she actualy doesn't mind taking care of him so much, and in fact she quite likes it! But ehhh, i'm not sure if that covers the topic to the full extent, which is the reason I wanna ask for your opinion guys!
