Gonna break this and be the first one to say that worthiness depends.
If you read the op you'll notice he talks about trusts and looking for an EU group, this suggests he doesn't have friends to come back to and let's not forget finding eu groups is very difficult on many servers. Add that this person quit at the start of SoA and there is also the issue of having gear that should be quite outdated from weapons to boots.
So, either some eu people from Cerb show up to embrace him, or coming back depends on the expectations. Trusts only help so far, at some point there are a lot of roadblocks to a solitary progress.
