Once the party gets to the citadel, Corry says, "I can actually be pretty sneaky when I have to be - Mom and Dad always taught their kids to be careful and able to hide...they were slaves in Cheliax when they were young...Shall I help her scout? She isn't really doing it very quietly..."

I'm not sure if @samduke meant to roll stealth or not, but Corry has a +5 on his checks. I would offer to scout, but don't want to step on toes...

If it looks best to have Corry help, he will sneak up to scout the same places as Ophilia with a (1d20+5)[19] Stealth and Perception at +5.
