Dr. Palmer
Christine will answer the call to assist with patching folks up if needed. Fighting zombies? Not so much. Definitely not at all. She's seen those horror movies at least once. Maybe twice. Three times is probably pushing it just a bit.
Either way, pop culture has taught her to look for bites, which thankfully aren't present. Cue a very deep sigh of relief!
Like any good doctor, she brought necessary first aid items: antiseptics, bandages, suture kits, gauze, medical tape. Anything worse and she'll be ushering you to the Med Bay. Don't argue with her because she's worked with the likes of Stephen Strange. She can handle your sassy ass.
So, if you want a Dr. Palmer special (...not that kind, don't be rude! You're not Stephen), that's cool with me!
