Tommy would have left it alone, but when Callen had disappeared, he hadn't said anything. He had barely known Sean then. Now, he couldn't do the same, even if he probably should have. After all his track record with talking to friends wasn't that great. However, when Savannah dragged Oliver into yet another isle, Tommy got closer to Sean. "Are you okay?" he asked. "Actually, you don't have to answer that. I know how it feels to lose someone you love. If you want to talk to someone who isn't family." He left it there, giving Sean the chance to talk or not as he liked.
