Andromeda: Got on the roof with a sniper rifle ready and a drone en-route mapping the building before anyone else even had a chance to get out of the clinic!
Silk: She's a really nice person and deserves quintuple karma.
Noise: The way she acted when alone with Silk... from the acting to starting the shooting, it was fun. The Russian did a lot to add to Silk's credibility to con the guards, good thinking! (Also, damned great pic!)
Little Joe: Scary, scary little girl... Picture's awesome. Coolest moment was pretending to be the Johnson... Good thing Silk wasn't there to witness it. The very descriptive way of finishing off the guards while feeling the life slip out of them was pretty vicious too. (Man, our characters are so going to have problems with each other.)
Still Waters: Gets point for constantly being in a bad mood and for very descriptive spellcasting. Putting spells together out of bird crap is so much cooler than just "I cast this or that spell."... Then loses 294 karma for calling Silk a skank.
Hank: Had a lot of fun reading about that dwarf and his ego

It's not a specific moment, just the whole thing... from immediately feeling personally mocked by the add at the clinic to the way he struggled to carry the target but still hopes to be impress... I laughed a lot really. Also just might be the only trustworthy character in the group. Or is the best actor of all of them.
I/O: For completely pissing off Silk by messing up the negotiations, then making up for it by promising her extra pay, then leaving before giving her that extra pay... damnit :p
"Silk: I liked the exchange between Silk and the Delta-Grade-Cyberninja/Hacker"
Bah, she would have pwnd him if he hadn't turned off his ears when running.
