Thor just nodded with a slight smile. He stayed up to make sure his brother got to sleep and then, when that happened, let himself drift off. He was pretty tired as well after minimal sleep due to worry. And it was comforting having Loki's arms around him and his head rested against him. It helped allow Thor to sleep, knowing for now that his little brother was safe and alive even if terribly ill. He was fast asleep when Loki woke during the night, but woke a bit earlier than Loki did the next morning. Maybe it was some kind instinct. He smiled slightly at Loki when he woke, smiling more when he just curled up close to Thor and closed his eyes again. He stayed still where he was, so not to disturb Loki, feeling surprisingly refreshed even though he hadn't slept all that much.

Tony had gotten maybe a few hours of uninterrupted sleep but soon the nightmares had returned, waking him up constantly through the night. He did catch an hour or two in between each but by the time it was 4am in the morning the intervals were so sparse that he just gave up. It could have been worse, though, at least he had slept some. There were many times when he just didn't sleep at all. He was now nursing a bit of a hangover, nothing major just a small headache. He had had much worse. This one was really nothing. He ended up staying in bed for another hour before getting up at 5am. After a quick shower, something he really needed, he changed into fresh clothes (he had no idea how long he had been in the ones he had fallen asleep in) and headed out into the kitchen area. He wasn't really that hungry but he made himself some cereal anyway. He ended up playing on one of the electronic pads (similar to an iPad) that he had made, one of many in fact. He often skipped breakfast and went straight to work but decided it would be a good idea considering his lack of sleep. He had gotten some, but not enough. 

When he was done he just stuffed the bowl into the washing machine, returning to the pad and opening up an app he had programmed so he could make blueprints electronically without being in his lab/workplace. Moving things around he began to replan out parts for a few new Iron Man suits he had planned out, as well as extra gadgets to help all of the avengers. He got so drawn into the work that he didn't remove himself from it until it was later on in the morning. It wasn't extremely late, probably about nine, but he put away the pad and moved towards Loki's room, knocking on the door quietly and peering in. Thor turned his head to smile slightly at him, but also indicated for him to be quiet in the hope that Loki was asleep. Tony nodded, mouthing to Thor to ask if he needed anything.
