Merlin hadn't been kidding when he'd said he'd know where Zacharias was. He left work, hopped on his broom and just flew until he felt his anxitey go nuts and knew it was time to land.
He didn't know what Zach wanted from him, not really, but he'd been made uneasy by the mention of sex and hoped that all the other man wanted was lasagna - it wasn't really even about the broomstick polish anymore, but something that Merling still couldn't put a finger on, some instinct that told him that this was something he would do, one of those moments in his future that he had no control over.
He alighted on a balcony and knocked, knowing it would be the right flat.
