As soon as Isaac heard Lydia's voice from behind the hut, he had a feeling that he knew what was going on. Malia was suffering from sickness as well, a lot more than he had expected and he had expected a lot. He spent most of the time making sure that he was holding her hair or trying to take away some of her pain or discomfort, but right now she seemed alright and Isaac wanted to check in with Lydia - just in case. Stiles comment about forcing Scott and Lydia to interact concerned him, but even more so that he knew Scott was still bad talking people. Scott, who told him to go fuck himself. Isaac worked hard to avoid taking sides. Scott had made the decision for him, though, in the end. He waited patiently for Lydia to come around the front and put her things away before returning to him, and he waited for them to walk a short distance from the hut before he lifted a hand to place it on her shoulder. "We can just sit down if you want to, Lydia, you've been getting sick? If you're still nauseous I can just let you go to sleep, I don't want to keep you awake."
But she had continued, and Isaac's hand fell away when she mentioned the blow out with Scott. He immediately felt his heart sink into his stomach and Isaac's hands slipped into the worn pockets of his jeans, his eyes falling to the ground beneath them. He didn't know exactly how much Lydia knew about what happened with Allison, less than he thought she knew, that was confirmed when they spoke at the bonfire. But knowing that Allison confessed her feelings for Scott, knowing that she didn't even glance at Isaac as he watched on after seeing her getting impaled, he didn't want Lydia to know all of that. He didn't want her to live it. "It's fine," he responded a little shortly, not with annoyance but with anxiety. "It's fine, he's just been bitching about it for too long and originally, he said it was about respect but he hasn't even tried to reach out to all of the people he considered his 'pack' at once in the first place so... apparently it was about getting laid. Or it was about respect that he doesn't want to work for, it doesn't matter." He was purposefully avoiding the way that Scott spoke down to him for leaving. He was afraid of what he would say if he acknowledged that part. "I don't have to tell you how I feel about it. Obviously you saw."
Isaac swallowed hard, his throat having gone dry, and he glanced back at Lydia. "How do you spend the morning getting sick and still manage to look good? Are you in pain?" He gave her a look before she responded. "Don't lie."
