Since Tristan already walked out on them and it seemed that he had no plan of continuing this conversation, Hannah and Andrew had no choice but to leave his Condo Unit.
Hannah regretted her actions. She felt like she's the reason why Tristan's mood was ruined. Instead of fixing everything, their conversation didn't end so well.
But she couldn't believe that Tristan would defend Lillie to that extent. He was hell-bent to take all the blame so that Lillie would not be involved.
But for Hannah, Lillie was already involved here. Now, she wondered if Tristan was as protective as this to his other women.
"Let's go. I think we also need to talk." Andrew said to Hannah.
He decided to talk to her. He listened to Tristan. Maybe the right thing to do right now was to tell Hannah the part when Lillie stopped and admitted that she was reluctant to do it with him.
