Just an Ordinary Day in the Life of an Ordinary Girl

The two of you keep silent all the way back to the house, but approaching the steps that lead to the front door, you start speaking again. "I know we're gonna be so happy here, Thomas. I'm so glad we finally don't have to pretend anymore."
"Me too, darling. Me too."
"Still, I feel bad for Margaret," you say softly. You can't help but feel pity for the woman who felt so betrayed by the two of you, though you know that you did the right thing. True love can't be wrong, can it?
"Ammy, don't worry about it. Okay?" Thomas puts an arm around you and leads you inside.

You know you've never been inside the house before and you're overwhelmed by the splendour of the huge interior.
The space is lighted only by the power of some torches and candles on the wall. Tapestries cover large pieces of wall from roof to ground. Soft red carpet covers the wooden floor.
Some meters before you a staircase offers an entrance to the first level, which is supported by firm wooden pillars in the back part of the hall. In the front part you can see all the way to the top of the house, the ceiling painted with tinsel and a tinge of mother-of-pearl.
On both sides of the stairs, on the ground floor, there are several doors that must give way to many different chambers. And you guess there must be some behind the stairs too, but it's too dark to see anything. Though, for a brief moment, you think you see a figure standing there in the dark, but you can't be sure.

After having given you some time to take in your new surroundings, Thomas disrupts the silence and says, "I'll take you to your chambers now so that you can change."

What do you do?
