Merlin nodded yes and then reached to get his cloak before stepping out and making sure the door was locked behind him. He only hesitated briefly at Zach's outstretched hand before reaching out to take it, his grasp tentative like he was scared that the blond would hurt him somehow, crush his hand or, worse, not let him go.
Luckily, Merlin could see that he was being irrational and he kept his crazy thoughts to himself. "Thank you." he said, ready to go.
