I lovedlovedloved the way their relationship developed in this episode. & the singing! & Clara being wonderful and the way she knows who she is and is so confident in it. & Eleven's character development too; I love that SO much.

There were a couple things I'd've changed (not about Clara & Eleven, just about the way the Big Bad of this episode just...didn't work for me), but I definitely thought it was a great continuation of last week's pretty strong start.

& Clara's speech at the end made me really want her & Martha to meet. Or her and Donna. Or you know, ALL OF THEM.
