This is a little different than previous posts on this. Mostly I want to know where the rolls come into play and how they affect anything. It says under sleight of hand you can draw a concealed weapons as a move with a penalty. I always thought you rolled when concealing, not when drawing. How do I resolve this scenario:
Han has a dagger concealed in a spring loaded sheath. He decides to throw it at Greedo. He draws the weapon as an Immediate (Swift) action and attacks. This is the surprise round. He also has Underhanded rogue talent.
I guess Han rolls sleight of hand vs perception when drawing the dagger. If Greedo spots it, he can go on the initiative, but Han has already started his turn, so his initiative seems moot at this point. Does that prevent Underhanded from triggering though since Greedo spotted the dagger?
