Look - he was due to show up any day now - just no one knew exactly when.
You know, I never even noticed that Jesus was missing.
Half my problem with it is the lack of reference. The fact that they never said he was dead, or where he was (perhaps he was away in another universe), means that he probably didn’t exist, or wasn’t resurrected according to whatever biblical story they are otherwise basing their universe on.
I think it could have been made fun, cool or throwaway. Technically he was bloodline of god, so could have been the way out. Much more so than the son of an arch being as powerful as god.
