I';m thinking good but not great, not Rei standards but not some shifty homeless bum with a shiv (both of which can come later). And I like that plan, I'm thinking no doubt he'll get close, Alessandro maybe moves just before he's skewered or something but is grappled, knocked down/knocked out somehow and thats when Rei shows up and kicks arse. Alessandro isn't weak and utterly helpless after all. Just rather trusting despite every reason not to be.
