Eh, Jacques is a pretty effective fighter, so I'm not too worried about him. Even if he did die, it's not like he's my favorite character, or anything. Heck, I barely use him. And every plot he's been in has died, so there's no real investment there.
Still going to wait for a third party member, though. Jacques is good, but those guys look like they're either Cyberpunk or magical, which tend to have an edge over a mundane (if badass; about on par with Boris though with a different combat focus) human soldier.
