After washing Rafael's hair, Annalise returned to her bedroom and only came out when it was time for dinner. She turned down the offer to eat with the Callahans and ate with the servants so she could avoid Rafael for a short moment.
Rafael taking Siena to the ball puzzled her long after she had finished washing his hair. If this was some game to make her jealous, he was taking it too far by asking another woman to be his partner. This was strange for Rafael since she didn't think he would stoop so low to take another woman to the ball just to make her jealous.
Unless there was some truth to him toying with her. What else was she to think when he was taking another woman to the ball after admitting to still having feelings for her?
Annalise tried not to think about it so much since it should not bother her. She didn't need to think so much about what Rafael was doing since she rejected him over and over again.
