Marco has to be deleted by SeJu, not JW as they have never made allies so JW couldn't see Marco. But SeJu seemed to be traumatized, psychotherapy was needed, so seeing him return to the game just to delete the last bug, Marco won't be his cup of tea. I anticipate second season. After few HJ logins and she held no weapon, I knew and didn't think she would be playing the game like JW. She only logged in to find JW location, meet Emma and find clues to help JW. But second season, I could see HJ wanting to find JW, she would be going and playing as actual player, holding weapons, leveling up and all. Her brother SJ can fix or find out why, how the game got messed up. I welcome that idea.
