He got out of bed, and it was unusal because normally he'd have to force himself to get out of his warm covers. He wondered if Thor was awake yet, most likely not, the man went dormant in the summer. Either way, he crept quietly through his room, pcking out his clothes and making his way - Trying to creak as little floor boards as possible - to the bathroom at the end of the hallway.
He took a shower, getting out all the sleep tangles in his black hair. He got out of the shower, pulling a towel around his waist and combing through his hair lazily, trying to make it curl less than necessary. He slipped on his favorite green button down shirt that was so faded it was actually white mixed with the slightest hint of green, and his favorite black skinny jeans that were also shamefully faded to dark grey. He needed new clothes. Wringing out the excess water left in his hair into the sink he made his way out of the room and down the hallway to the stairs.
The stairs were the most difficult part of his journey, being that the house was at least a hundred years old and that everything was wooden floored. He took them each carefully, contemplating whether to slide down them on his butt like Thor used to when he was a child - child being about a year ago - but deciding he'd rather have Thor catch him than do anything like that. Finally he made it down the stairs and jumped lightly when he heard a snore come from the living room. Creeping over the couch he found Thor, sporting his neck in most likely the most uncomfortable position imaginable, and deep in his dreams. Loki smiled slightly to himself. Thor looked so much more innocent when he was alseep. He shook the smile away, walking into the kitchen and getting a piece of paper and a pen and scribbling a note.
Went to visit Tony, won't be gone too long.
He knew his parents were out of town so he didn't have to worry about facing his fathers wrath about finding the note, or sneaking out without telling anyone. Thor would hopefully be okay with it. He'd done it enough times that he should be okay with it.
Grabbing his sweatshirt off the hanger, he opened the door quietly and slipped out, leaving Thor to play with his dreams.
