I only just noticed this thread because I suck, but I'll just go ahead and answer all the questions now anyway to try and suck less.
Question 1: In the past when I was running with Lexi I usually came up with ideas myself for whatever I thought would be a fun little story that week for her, and get feedback from others to expand the idea more or tweak it as need be for it to make more sense. With Callie (even though it's only been once so far), Jam came to me with the idea and then we went back and forth talking to expand it a little bit and make our RP's longer. Also usually I put music on but sometimes I just need to put the TV on something I'm not interested in and just use it as background noise.
Question 2: Off the current roster I'm not sure as I'm still learning about most of the current characters that weren't here last time I was. But for a dream match, if The Clark Sisters ever end up having some good success it'd be badass to face Cerberus.
Question 3: Callie obviously is spending KC Weekend with her sister Gabi. They are extremely close and they're tag partners.
Question 4: No clue, I've never been good at this type of thing.
Question 5: Outside of Gabi, I could see Callie getting along with someone like Batti despite Batti being face and Callie being heel.
