Caesar will help...! To an extent, anyway. If Nephry needs help organizing things, he'd be more than happy to help out as much as he can. If it's just manual labor, his participation would be a little more limited (because he'd be more concerned about the area surrounding his house, and he needs to save his energy to deal with that!!).

Orphen (trollkiller) will also help! He would actually prefer to have an in-charge role, because it means he'll have less work to do himself. :'| Either way, I'm not too picky about what they do, but yes! They will definitely help out. o/
