Yeah, I doubt that there's any relationship between the "-getsus" - that'd be like saying that Hitsugaya and Ikkaku are congenital twins because their Zanpakuto both have -maru in their names, or that Omaeda is Ichigo's father's uncle (Gegetsuburi).

But yeah, Aizen is definitely afraid. If he wants to stand a chance, he needs to lose the god complex and look at Ichigo as an equal, or at least as a threat.
