You do realize that he was twelve at the time, right? And besides, that would be Greenscale. He's got purple wings. (And eyes.)
Also, he did hit the characters in that fight. Both Radic and Janine ended up in the negative HP range despite their buffs, and Matt was brought down to 2 HP when he ran for it.
Oh, that would be an absolutely wonderful idea, if they knew where he was buried.Oh, he's dead? Well, it's utterly impossibly to ask him then. (Eyeroll) Just Speak With Dead on the mercenary.
