Could you post a scan? For those of us who haven't read either source material and are relying on this topic. It sounds to me like Kan is saying Darsh has protection from someone trying to reality warp him directly, but hasn't been shown to have the same protection from say, someone ignoring him and messing with his ancestors.
I'm also still wondering how Darsh is going to actually win. I can see where everyone is coming from when they say he can block most or all of what Prime has, but I don't think anyone has mentioned how he'd hurt prime back?
