The two of them didn't go to sleep until Alex came back.
"You can sleep on the couch here," Percy dropped a pillow on the arm rest and looked up at him. "The water is right there. And Tiara and I will be in that room."
"Together?" Alex blinked. His face was pale and he looked like he had just come out of a dumpster. His hair was messy and there was a slight distorted sheen to his eyes. Percy wondered where Alex had gone.
"No, we need to be together to Connect and travel into the game," Percy reminded with relief. So they don't have to go into the game every time they slept! If they sleep apart then they both can sleep normally.
Percy felt at ease at this realisation. He bid Alex a shaky goodnight before helping Tiara brush her teeth and lying her down on the bed.
