Her eyes slid to the bathroom door as he explained what was going on, vaguely remembering using it as something more than a powder room back before she had been turned. Her eyes went back to him as he offered her his hand. She'd much rather have crawled to the bathroom, judging by how little she now wanted to move, feeling like she would burst - but it would have been rude to deny his hand, and she was grateful for him wanting to help (and not just laughing at her.)

So she took his hand to be lead to the bathroom, feeling much like a child again as she did do. 

Once she had reached it, she thanked him quietly and shut the door behind her. She spent a moment looking at the porcelain contraption before deciding to just sit on it. (after lifting the cover)

it may have taken a while for her to get from there to washing her hands, but kudos to her everyone, she managed to do it.
