Andy had seen Inception; he wondered if this was how it felt when the dream collapsed.
He stilled when Taj said he needed to do this, because as much as the world was crumbling around him he'd never stop Taj from doing something he needed to do; he'd meant what he'd said when he'd told Taj that. He just wished Taj knew that he was smart, that he'd had nothing to hang his hat on but had still managed to work things out; it was his lack of self-belief that upset Andy the most about that, but if Taj thought this leaving would help that then he wouldn't stand in the way.
It was when Taj denounced their brothers that the grip that had been tightening on Andy's heart crushed it between phantom fingers. He hadn't seen his brothers change but here Taj was saying he couldn't bear to be around them, that he had no peace. It cut his heart to know that Taj must have been speaking about him as well, because hell knew there were things that Andy kept from everyone. As cut and crushed as he already was, this guilt just flattened him.
He didn't know how to fix it because he couldn't find the problem. He couldn't fix it because he was the problem. Hering that he loved them but still couldn't stand them panicked what was left in him that could still be panicked because hadn't Taj been telling him that only a moment ago?
How could he be the only peace? He felt so bad for Taj, that he'd been driven to this untrustworthy, unpeaceful place and that it had been his fault that he couldn't hold it back. Taj revealed that it was already done and in motion without a chance to talk it through and Andy's face ran wet with tears that wouldn't stop, slipping fast and full down an otherwise blank face.
He nodded and backed up, getting off the bed and unable to even lift his head once he had.
"I have to, go, I'll go, I have to just, I'll go now okay." he babbled thoughtlessly as he began retreating from what he'd done to Taj.
