"Sometimes it's hard to see self-worth," he began, relating to that comment as he spoke. A little sadness came over him but he had to help Ava, he was not going to let it show. "But other people remind you of that by showing that they think you deserve their love." If she wasn't accepting what he said to her and she wouldn't go somewhere else then he had no idea what to do. If someone like Titus was there, it would make what was said more meaningful since he would be explaining why he loves her, not why Hal presumed he did.
Hal did not know Ava that well but he could understand how she could be a handful to look after. "Does it not prove to you more that people have stuck around and not run away from you?" It was asked as a question but meant more to show how wrong she was. Not bailing on her showed that she was loved but the why could only have been clarified by her adoptive father.
