Backlash is on Alpha and they share a handler, so they'll know each other! He's kind of like the obnoxious big brother who gives advice when it isn't wanted and pokes at people's buttons for fun and sometimes has fun ideas that makes his pain in the ass-ness worth it. He'll keep an eye on Liz/Beth especially, because healers are important and Alpha needs to keep theirs!
whosthere will be fascinated with Liz/Beth once he realizes that she is in fact two people. I don't think he has been around long enough to realize it, so maybe it can be something he figures out in game!
gorgonn is kind of in a sassy I'm a brat mode right now, but I think she and Beth would be able to make friends if they got to know each other in the right setting/way. I don't think she'll get along with Liz as well, which could make for some interesting confusion!
pixieled is deeply dedicated to GC and has pride in her work too, but she has been in the program for a while and probably knows about Liz/Beth. I think she keeps her distance, though Liz could make for a fun bad influence on occasion, maybe!
