"We were going to," she pointed out to Magius. She wasn't sure if Mr. Snape could help her, but she thought she'd go see about that first before engaging in any actual magic. Maybe if she could start from a calm place at least, there would be less of a chance of accidents.
"I'm going to go find Mr. Snape," she informed them, since it was rude to wander off in the middle of a conversation; even she knew that. "It was very nice to see you Magius, and very nice to meet you, Mr. Didymus," she said politely before she started to walk toward the archway leading out of the kitchen/dining area.
"I'll see you later though," she called to both of them. If she really had been missing though, maybe she should go find Lizzy first. The other girl was probably wondering where she'd been. Yes, maybe this was the better plan. Lizzy, then Mr. Snape, then Magius again.
