Adrian wasn't thinking about the idea that Maybe Katie hadn't told Ali about her and Graham. He knew the pair weren't exactly on friendly terms, but they weren't exactly in the forefront of his mind right now. His concern was all for his girlfriend and son at the moment. He didn't have much room for anyone else.
"I understand," he told Ali, because he did, even though there was a little bit of a pout, because he wanted to be selfish and keep her here with him and Ryan. He agreed that Ryan should stay here. He was already asleep. Adrian had no wish to wake him.
"Gray could always see her home," he suggested slyly. Knowing Ali, she wouldn't want Katie going alone, especially right now. He was sure his friend would welcome the opportunity, though, and if it would get Ali to stay, he wasn't above making the suggestion, regardless of whether or not Katie was likely to be a fan of the idea.
