Does that mean he should remain in oblivion though?

Alvarr wasn't even mentioned in the episode. If you think it's okay to just completely forget about a character then that's your mind, but I don't like plot holes and cover-ups so I in my personal opinion, I think Alvarr should return to finish what was started.

He's not a character like Nimueh whose story-arc has been completed. Alvarr's story was left off at him running away from Camelot. I wouldn't mind if he just appeared for 10 seconds and then died, but as long as his story-arc is complete.

Same goes for Tristan... and same will go for Sefa is she doesn't appear again though I'm almost certain she will...
