Dean raised his hand after even trying to suggest sleeping on the floor before he looked abruptly at Sam who muttered before declaring that he was going to take the floor. He had to stop him right there.  "No can do. International Dibs rule, I'm taking the floor. No ifs, ands, or buts. I already moved my things so I take floor. Sam keeps his bed,  Evie tkes the other bed. Now! I'm going to bed and you all are doing the same! Goodnight." Dean said as he grabbed him some clothes to change into pajama wise and then made himself a bed space between both beds and got comfy as one could get before slowly going to sleep himself. 

When morning hit, Dean was up about 8 a.m. and went to take a shower,  having remembered that he had blood and gunk from last night and hadn't showered. Taking his time, he eventually got out, changed, and did his morning routine before exiting the bathroom and packing his things up while letting who were still asleep, sleep.
