I think it would be best for all involved to give Missionary/Retcon (I will use Retcon because it is the oldest of the accounts) a chance to redeem himself, and for all parties to terminate the inquisition against him.  Using a sockpuppet or changing to a different account to escape unwanted criticism is permitted at Wikipedia.  If his actions had been limited to that, I would not have responded to Tommstein's request at all as an ill-founded request.  However, what led me to respond were two factors: one, that Retcon had fraudulently attempted to mislead people into believing he and Missionary were different people, and two, that he created at least one impersonation account, impersonating a person who he was clearly at odds with.

In any case, Retcon has acknowledged and apologized for his inappropriate acts; Wikipedia's "assume good faith" policy all but requires to accept his apology and move on.  So let's please do so.  I'd especially call on  and  to lay off the rhetoric; it will not help defuse the situation.  Personal attacks (such as  calling Retcon a "compulsive liar") are neither helpful nor welcomed.  There is bad blood on both sides of this issue, and frankly I'd like to see y'all work this out on your own with civility, rather than escalating the situation to the point that intervention by the Arbitration Committee is required.
