I red some pages of the Return Of Wolverine trade and i was drawn by two panels of the first issue. In them, Wolverine (with amnesia once again) says that he heals pretty quickly but he also states that a wound on his side was not healed and he could say why that's was happening.
I am away from the X-Verse for some time (ever since the Bendis years) and i do not know the whole scoop regarding Logan's resurrection. So can someone answer me if Wolverine's healing factor is completely restored and how it was restored?
