When April woke up from being knocked out, she was inside an unfamiliar room. The room was small and she could hear water waves from outside the room. The room also moved. If her instincts were right, she's on yatch.
She tried to recall what happened before she lost consciousness. That time, Alex and her had a serious talk. She ended up walking away, hating Alex for what he did.
Although she acted bravely by sending that reply to Francesca, it still made her heart bleed. She knew that it wasn't Alex's will to sleep with his wife, yet he was still at fault for keeping in contact with her. Yes, she felt that it was wrong. Although the two were still married, the divorce had been in process. Doesn't that mean that their relationship should be over? She didn't believe that Francesca was suicidal. If someone asks her, she would say that it must've been a trick to lure Alex to her side.
