So, for my next session, rather than create our own characters, our GM gave us already-created characters, and by luck of the draw, my character is a newbie to the whole hero game. A lot of times, if my group is playing any new characters, there aren't any rookies; the new guys tend to have a minimum of 2 years experience out in the field.
Thing is, I'm not really sure how to play a newcomer (other than saying, "What's that, [teammate]?" every two minutes). Any advice for how to play him? BTW, for reference, my character's essentially a mashup of Deadshot and Red Arrow, with wrist-crossbows instead (in other words, a gender-swapped Quarrel from Astro City).
