You begin searching for her

You check around for signs of Mrs Figg. You enter her bedroom where you can see your aunt's house. You stare on for a while and slam on the window with anger. You turn back and you see a flask that resembles greatly to the one that Marge used. You inspect and you see breast pump under her bed. You came to the conclusion that the liquid which turns on everybody was, in fact, Mrs Figg's breast milk. You check her drawers to investigate more where you saw pictures of her not only naked with a cat but a cat you remember quite clearly. It was McGonagall's animagus form and in the next picture, you see her and Mrs Figg enjoying each other. You miss Hogwarts more than ever, but the priority to subdue everyone comes first.

You check around the room for more clues and as there were none you then start searching for Mrs Figg to confront her. You hear voices in Mrs Figgs bathroom and you take a peek.

It seems she expected you.
