I was wondering that, and annoying my mum asking her what happened, even though she only watches it on a Thursday, generally. I bet she thought, "Get back on the soapboard and stop annoying me." The only other let down I thought was the very beginning, and I wasn't expecting Phil to carry Ben out like that, but for Ben to be asking him to go outside.
I couldn't believe that they had Stella telling Phil exactly where she was and approaching him on that roof when she knew that he wanted revenge, without letting us know what actually happened in Stella's childhood, apart from her parents rejecting her.
