Hayato can't look Ryuutaro in the eye during the explanation. He was afraid. Afraid he would see regret on his lover's face. Afraid there would be contempt for him. It had dawned on him that as long as Ryuutaro was with him his life would be in danger... his world was more cruel than Ryuutaro's. When things settled down some he would talk to Ryuutaro. He needed to know the dangers of this world before he made his final decision... and Hayato loved him enough to let him make that decision, regardless of promises they had made.

Though these thoughts are quickly forced away when Ryuutaro brings up the machine. His head snaps up and a weak smile spreads across his face.

"Right the machine! Ryuutaro had a vision! He saw a machine that held our future selves in it! Irie Soichi had it! It's gotta be what's keepin' us here!"

There's a wave of surprise and some muttering for a moment, then Reborn looks up to the blank center of the map and smiles.

"That must be in the guarded chamber here..."

Gokudera smiles at Ryuutaro, and proudly takes his boyfriend's hand, stepping a bit closer to him.
