That would depend on the nature of 'over his head' and possibly what you mean by 'who'

For example most issues can be taken care of by summoning entities that can solve the problems for him either by being big and mean or knowing about what he wants to know. 

So I suppose do you mean a go to summon or more of an ally to give him a safe haven? Or should I just get a hand full of demons he uses and an ally?
