"On the provision that there is no outside help for either party at all," Izzy follows up. Feeling like that is a very important caveat.

Lucius knows a fair few aboard and could easily employ their knowledge. This needs to be a fair fight or what would be the point of it.

Only when his condition is met does he hold out his hand, only just managing not to spit on it before as is the old way. Somehow he doesn't think Lucius would like that very much and to be honest, Izzy can't blame him. It's kinda gross.
