She notices his jacket is there. A part of his presence there on the couch which gives off the same aura. She possibly took it to keep her safe and got herself water. Depending on when she goes back to bed, she will or will not see Aerius enter back into the apartment and folding his wings back up to his back. He does notice his jacket missing from its original place. If Giselle is still in the kitchen, he sees her with it and mental cussed himself out. If she is back in her room, he closes the window and peaks into her room. If she had it in the room, he lets her have it and explore the apartment.<br/><br/>From his wings and moves, one can tell he wasn't human but it wasn't a fallen angel nor a demon. He was half Angel and half demon. His story will be revealed later.
