Minho called dibs on top bunk, so Thomas is on the bottom one. Teresa has to sleep in a separate room (no girls allowed, we guess).
As Thomas is falling asleep, Teresa checks in using their telepathy and tries to make him feel better about losing Chuck. He feels like it's his fault that Chuck didn't make it, and also like he's lost a brother. Teresa tells him not to waste the sacrifice Chuck made.
After their conversation ends, Thomas rolls over and feels almost happy.
