Disclaimer: massive spoilers for the series finale. Triggers for pretty brief suicidal thoughts. They both know it. They say it to each other in looks and tentative touches, when House is rubbing Wilson's back when he feels as if he's about to hack up his lungs. In those moments, he doesn't have enough headspace to think, "House loves me," but sometimes he doesn't have to think it. Sometimes it's just his touch on Wilson's back and a few gentle words swathed in sarcasm. He knows. They both know. And what if Wilson was a star? And what if House was the universe, and what if he loved Wilson and let the oceans of time dwindle so he could be with him; only him, forever? What if there was a utopia?
