Upon hearing some noise, she wasn't sure if someone else was in the house. If they had broken in or what. It would unlikely but not utterly impossible. Hermione stepped along though the hallway until she reached the kitchen, the source of the clatter. "Are you alright?" She questioned. It seemed like he was about to say something but stopped himself. She remained outside in the hallway, looking in. "Well I'm going to get to work now, I should be done in about an hour or so." She said. It was a simple potion, yes, but the female wanted to double check her work. It would be beneficial to them both so making it perfect was a dire condition. Of course she didn't doubt her skills or Lupin's trust in her but she was a perfectionist at heart and wouldn't take the task lightly. With that, she continued and headed up the stairs to her room.

Looking to Rose and then back to the woman, the Doctor put on an energetic grin. "Great." He nodded. Of course he already had some suspicions but at the moment, they couldn't poke around too much and blow their cover. Their next move was to do more investigations, see if they could find actual fault with the product itself. They would need proof of course. They were given a list of the names of people who had just signed up for the product. They were told they could contact them if they needed to. Other than that, it seemed the tour was over. "Thank you for your time, we'll be in contact soon to discuss signing a deal together." The Doctor said and motioned for Rose to come along with him. They could pay one of these people a visit and do a bit of digging.
