Jamie will be just as worthless as he was in Trost with controlling you, Alan. Though... this could be what echos back Trost for Jamie. Sadly he wasn't around for Reiner and Eren's big stupid titan fight and Eren had more control by then. I'm thinking other castmates have more potential of helping you than Jamie does.

I'm still hoping to be involved but not involved enough because I'd rather Jamie's mom get killed off next season not this one (ie. echoing back trost)~

tl;dr, come to me if you think alan could use jamie but I don't think there is much he can benefit from. Unless you want another lecture. When he gets his 3DMG however there is potential cr with them if you're looking for another major before the season ends.
