What will Echo's specialty be? I'm curious how Echo is going to solidify into a member of TBB. So far he's done a little of everything but it doesn't seem to have a specialty necessary yet. His most natural fit is working with Tech for hacking/repairs, but it seems like Echo is mostly just serving as the interface in that case (meaning, Tech could probably just fashion a dataport tool himself and just do it on his own). He also seems to be pretty good in combat but nothing special compared to the rest of them. 

So I'm wondering what Echo's role on the squad is going to be, beyond being a weird clone. Otherwise, he's a reg. It seems like meeting up with Rex is on the table as well, so I guess their relationship will be a big plot point as well.
