Well - my first thought is certainly...I don't understand this from an IC RP concept. How would my character, who isn't pulling up your character card, know all these things about your character?
I mean wouldn't you find it a bit strange if a new character ambled up to Leff and started talking to them like all their history was known?
I already find it hard to not mention character's names if we haven't been introduced just because it can feel a little...redundant since their character's name is there in the window.
