Merlahad Concept 2/? -
Eggsy’s MIA, presumed dead, and it’s the last straw for Harry. He disappears without a trace, leaving Merlin behind in an equally broken state.
Merlin traces Harry’s possible whereabouts, calls regularly, hoping Harry might one day pick up, and goes on with his life the best he can.
Harry shows up at the government tech agency that now employs Merlin to tell him he can stop his searching, because Harry doesn’t want to be found.
