Katie couldn't have told you why she didn't let go of Graham's hand as they arrived. She'd hated the thought of having to hold it to begin with, but the truth was that it had been a rough night and the trip to her parents' home had done little to reassure her. She didn't like to show how it was getting to her, but that didn't make her any less worried.
"They're probably fine," she told him with false bravado, shrugging her shoulders as if she wasn't desperate to know that for sure. She didn't want to make it obvious, how worried she was, especially to him. Maybe she couldn't know for sure that he was a Death Eater, but she couldn't know he wasn't and everything she'd grown up knowing told her not to trust him, especially now, however unfair to him that might be.
"It's this way..." She focused on getting inside, not sure why she didn't just try to ditch him right here or why she didn't drop his hand like a hot potato the second they arrived in this spot. Instead, she held tightly and led the way toward the front door, silently pointing her wand at the door and unlocking it so they could move inside. She should be telling him he could go now, but the truth was that she didn't want to be alone, even if the alternative was the company of Graham Montague.
