Jason was beginning to see her less as a vampire then as a woman. And in his mind, you didn't leave a woman like this, and Jessica was fragile at times. It didn't take a rocket scientist to figure that one out. He would do his best to help out. It wasn't as if he had anyone waiting for him at his place.
He was actually relieved that she had said no, he didn't want to give up any of his blood but he didn't want her to be hurt either. Luckily the TruBlood stuff seemed to do the trick.
Jason didn't mind the fact that she was feeding, sure it usually irked him a bit but he knew that she needed it. He didn't know how much blood he took but it certainly had to have been enough. He felt like he could dance if he had to but didn't want to look too awkward in the situation, he likely would burn off some energy when she was in the shower though. He did nod at her with a small smirk on his face, trying to show that he didn't mind.
He couldn't help but to reach out and hold her shoulder gently before giving it a light pat, "Hey now. I'll stay the night to make sure we're both safe, alright? If you got booze I can probably stay up til sunlight." He teased with a little grin on his face, although he definitely wasn't going to be tired anytime soon. He had way too much energy right now. It was a pity he wasn't getting laid but he'd be okay running or jumping jacks or something.
He really didn't want to stay in Bill's room, as he figured that his sister had ... done that in there and it really wasn't something he wanted to think about. But the couch seemed comfortable enough if he needed to sleep. "I'm not sure either. But I'll hang, it's alright. May leave t' get a burger or something later but hey, I haven't gotten t' talk to you much. Maybe it's a good idea to get t' know you more after tonight."
Hearing her he gave a nod and as he walked by her he gave her butt a firm swat and started up the stairs before stopping, and shaking his head. "... I have no idea where that came from. I think I'm just .. psyched to be alive?" He muttered before apologizing quickly, "I'm sorry. Sorry .. Um, I'll go and look for somethin' to wear. You get cleaned up. I'll meet ya back here in a few." He added before heading to Bill's room and trying not to look back.
