Abaddon smiled a little at the sight of the angel actually cracking smile. He was sure that he'd just been privy to an extremely rare sight.

He nodded and walked up the cracked stone steps, pushing open the heavy front door and stepping inside. As he'd guessed, the library was scarcely populated. Just as he wanted it. 

Shooting a charming smile at the librarian as he passed by her, Abaddon ventured further into the library. The population dwindled to just he and Camael. He found two worn leather seats in the corner of the room, nestled between shelves of books. 

"Please." He murmured, gesturing for her to sit down before he did so.
