At the reassurance, Shannon gave Dean a small, grateful smile. She found herself even more endeared to him when he said he not only didn't mind, but wanted to stick around until she fell asleep. She'd never used a shotgun and figured that she might actually end up being better off with a water gun, but she didn't say anything. "Thanks," she said softly.
She tried hard not to bristle at the suggestion of a shower, because she knew he meant well and she knew she could probably use one, but it reminded her of when she'd first arrived and the Doctor had suggested she take one as well. Only, then, he'd been more than justified. She'd probably been pretty ripe after two months of bathing in salt water with no soap or shampoo. Plus, it was infinitely adorable that he was offering to give her something to sleep in if she wanted to shower at his room rather than cross the hall to shower in her own bathroom.
Laughing, Shannon shook her head. "A drawer? Psh, you better clear out a few closets," she joked. She thought about going back to her own room to shower, but had to admit that him giving her clothes was an idea she actually really liked. It did feel a little the same as he'd put it. Like he was her boyfriend and it was her first overnight. "I think we can hold off on the extra toothbrush and clearing out space for my shit for now, Dean, but...in all honesty, just because the individual rooms are safe doesn't necessarily mean that the halls are, so maybe it'd be a better idea if I do just take a shower here...just in case. As long as you really don't mind and you're not just offering for the sake of offering," she replied.
It was really sweet of him, she thought, to be willing to do or get whatever she needed to feel safe. Just being inside made her feel safe, if she was honest, but she didn't say so. She kind of liked that he cared. It reminded her of Boone when they'd first crashed, only far less pushy and annoying.
"Mainly? I need a nap," she said with an airy huff of laughter. As another yawn took her over, she stretched her arms over her head and then dropped them back down at her sides.
She stood and looked around the room a little more before resting her eyes back on Dean. She could relax around him and just be Shannon. She didn't have to be Shannon-the-bitch or Shannon-the-whore; she didn't have to be Shannon-the-damsel-in-distress or Shannon-the-manipulative-rich-girl. She'd been filling those pairs of shoes for so long that she hardly knew it was even still possible to just be herself. But, Dean didn't expect anything out of her; he didn't judge her. It was a really good feeling to be able to take off the mask again, finally.
