Lambert knew the story of Steve and Hannah. He didn't know the exact details of her, but he knew Paxton had a friend in the hospital who didn't bode well for recovery. The girl was very young and she was very dear to Steve. He visited her often and was constantly alert to any news from the hospital, as if waiting for news about the improvement or worsening of the girl's condition.
If Steve was a sports yacht, Hannah was a seabed anchor for him. If he was a balloon, she was a sandbag. If Steve was a sports car, she would have be a lock on his wheel. If he was a bird, she was a cage.
