Shiro’s still gone, and the team are taking it hard. No one became the Black Paladin, and they aren’t able to form Voltron. It’s been like that for weeks.
But then Keith gets hit. And Lance loses it.
The only reason he was hit in the first place was from jumping in front of Lance. The guilt drowns Lance. His anxiety was already off the rails (Shiro was gone. They couldn’t form Voltron. Plus it was just a really bad day for him), and Keith being hit was just the icing on top.
In the end, they end up putting Lance in a pod before he makes himself seriously ill.
When Keith gets out of his pod, one of the first things he hears is Lance screaming.
He’s having a nightmare in the pod, and they’re forced to watch in horror as he cries out. Eventually, his shouts die out, but only for him to start shaking uncontrollably as he has a seizure. The sight makes them all sick to the stomach.
