Even Sora was observant enough to realize that Riku had a hard time carrying him alllll the way up the stairs and he wasn't about to be even more selfish about it all. So he carefully pried himself from his boyfriend to sit on his bed.
If Riku had something to do he ought to do it now cause Sora was so not letting go next time he got a hold of him. He finally wanted to be held, and comforted, and feel loved and cared for right now. Riku was the only person he would be able to get that from within a hundred and fifty miles.
The dogs weren't sure if they were allowed on the bed, so they explored the room a little, sniffing at things. Fiver wandered out the door and over to Sora's room and back to sniff Sora again. Everything in here smelled like Riku though. So weird!!
