if this is gonna make any difference, brenna has a big gash up her leg and assuming conditions are what they were in the movie, i was planning on her leg getting infected and possibly her suffering from hypothermia.
karma and mercury would both go on the rescue mission and not want to be in the public eye (although cessily could be talked into it if someone was interested to do so). brenna would want to be in the public eye but she's technically not a member of the team (yet?) so it depends if people would let her.
