I don't think it is, personally. I think George said all the things she needed to hear right then. She was so crushed because she had just seen her father for the first time since she was 5. She very clearly had abandonment issues from him. Then George (who we were told by the chief and Ellis earlier in the season resembled Thatcher a lot) came in and said he would always love her and never leave her. I think it hit perfectly on what she was feeling after seeing Thatcher. Of course, George didn't know this was going on with her at the time.
this is EXACTLY why it was so shitty lol. she knew george was in love with her, and because she was upset and it made her feel good to know that there was this guy who worshipped the ground she walked on, she totally took advantage of his feelings for her.
SHITTY.
Yaaaaaaaaaaaassssss!!!! She exploited his feelings to make herself feel better. Such an asshole.
