He was about to reply that his funny feelings around Ginny weren't any of Keiran's business until he talked about that hole inside him like half of him was missing. As soon as Keiran had said that, Jackson realized that that was exactly how he felt. Sometimes he felt an ache deep inside him but had done such a good job in suppressing that he'd forgotten all about it except on lonely days. When he'd been younger and not so in control, the ache had been a near constant companion. At the time he hadn't known what it was and had thought everyone had felt that way.
It wasn't until he was much older when he realized that people didn't. But by then he'd actively worked on suppressing the feeling so it wouldn't make him feel like he was going mad.
Now all at once those memories returned and the hole opened up, yawning and hurting inside him only to feel... complete again with just Keiran's presence. It wasn't the feeling he felt for Ginny, that was something else entirely and this wasn't the feeling that he was attracted to Keiran. Instead it felt like he had just found his long lost twin. He didn't even think about how odd this thought was because right now it all felt normal by now.
"She's English," he replied feebly, looking over at Keiran with a sudden new light. "And yes, I feel funny around her. Like I feel funny around you but not like... I'm attracted to you. I feel like... I don't know. I suck at describing this shit." He took a gulp of his beer. "It feels like half of me was missing. Like you said."
