Zoro wakes up in the middle of the night. He got used to Sanji sleeping with him in his bunk and the sudden realization he's not there comes as a shock.
He's just on watch, Zoro thinks.
Is he though?
Does he keep it tonight?
He has to.
He surely didn't leave him - them again.
Right?
They will be the death of me.
Meanwhile Zoro next to him, nonchalantly: "we are really growing old together, dart brow"
Cue, Sanjis heart melting
They will be the death of me.
