Oh, Ardyn can complain about it. And he for sure does, the pain in the ass.

But if a little complaining was all it took for Angeal to give up on something, he probably would have stopped a whole lot of shit while very young. So Ardyn instead gets to do some nice hard labor for a while, alongside someone who stubbornly makes his bitching slide off his back.

Probably this is reason along for Ardyn to not visit Angeal too much in the future, but that's up to his capricious ass to decide.
