I caught up to this over the weekend by watching eps 1 -10 and OMG, my avatar should explain what i thought about it.
The moment when teresa was killed, i cant explain what i was feeling, there was this weird feeling in my tummy i was completely in shock.
This anime is great the fighting is amazing and Claire against that awakend male was awesome, i hope Miria teaches Claire how to become stronger as she seems to only be good against awakend ones, my guess is this was done on purpose in the hope of one day fighting Priscilla.
