Tyki doesn't know it yet but he's going to enjoy this overactive imagination that Rhys has. Things also changed rapidly enough that any information he might give to Rhys might just expire the next month. Far as he knows there is no fae that haunts dreams but who knows honestly.

Sorry, kid. Tyki can walk right through walls.

"You do know that I don't actually bite and that I was kidding, right?" This is Tyki now laughing at Rhys. It's both true and untrue. He just wanted to give Rhys a hard time for being fresh meat and giving him a bad first impression.
