Re: i. THE FRONT
Teleporting people around is no problem at all for Pixie. It's when she tries to go in fighting and using her dust that things get tricky for her. Unfortunately she's going to get knocked on her ass by one of those Sentinels and then one of the werewolves will be ripping at her wings.
Thankfully Nathan Drake will come to her rescue and get her over to medical. (and now I am running to work so others will be done later)
