Blimey. Al wasn't used to making difficult choices because, frankly, he never needed to before the village. He had a good heart and a good mind, but until his uncles popped him into their crazy world, he didn't face many big problems. Back home, choosing a college along with acing NEWTS and muggle tests for universities had been Al's biggest concerns. Here things were different. Here he was faced with his poor shy dad in kid form. He guessed he'd just have to follow his gut.
"Al," he supplied. Harry was opening his heart; Al knew because he suddenly felt like someone was twisting a knife into it. His dad was obviously nervous and way too thin to be healthy. He knew about his dad's past -- the basics anyway. What he hadn't known? He learned when Petunia landed in the village. Thinking about his dad as a defenseless little kid with those monsters made Al's blood boil, but seeing it just made him sad.
He knelt down so he was at eye level with the boy and flashed a reassuring smile. "Albus Severus Potter to be exact." He kept a careful watch to make sure he didn't send his dad running off Merlin knew where. "See, we're both Potters so if you need to tell me something, you can." He crossed his heart with a big X.
