Hmm trying to think of an alternative to confidence, perhaps Humor? Being a bit of a book worm I could see him taking a while for jokes to register- if they register at all. While Penmon is very playful, and would more than likely be the type to joke around, It could work to open Alex up a bit Alternatively he could potentaily need to work on impulsiveness, since I feel he'd be a little like my self at times, I spend to much time weighing the pros and cons. "If i buy this, now, .... or i could wait for... but I don't really need the other items...." Its hard for me to just Grab buy something on an impulse.
