Marietta's eyebrows - well, Hannah's, really - rose in surprise at Andy's remark, and her cheeks coloured (thankfully - if she hadn't blushed, it'd be a dead giveaway that she wasn't Hannah at all). She had no response that could possibly be appropriate without completely blowing her cover. That was it, she decided. She had to retrieve those bloody nachos. "Um...okay. Just...hang onto my drink for a minute or two, will you?" she requested of Quinn, giving him a very good carbon copy of a Hannah smile. "I'm going to get those nachos. It'd be a shame to let them all go to waste just because I had a full day." To add what she hoped was a bit of sincerity to this, she leaned over and gave Quinn a quick kiss on the cheek. "Back in a second."
She hurried out of the flat before anyone could argue, making her way downstairs, and within moments she found herself back at Hannah's flat. Rushing about as though her life depended on it, she got into the kitchen and threw together the last of the nachos, using her wand to make them look a bit neater, and then slid the casserole dish into a bag and retraced her steps.
When she arrived again at Quinn's flat, this time she pulled out the huge keyring from Hannah's coat pocket, but as it turned out she hadn't needed it. Everyone was still standing just as they had been when she'd left, probably stunned at how bizarre she was acting...but at least she had nachos now.
