He didn't sense her at all - definitely a nod to her runes, which would have impressed him if he didn't expect them or wasn't used to them. So the sound of her voice startled him rather abruptly...
"FUCK!" Thor cursed as he jumped and thwacked his head against the top of the refrigerator. Wincing, and rubbing his head he took a step back and stood up to his full six-foot-seven height. There she was, looking a good fifteen years younger than his body (something that always amused him) and just as fierce as ever.
"You need milk," he said, then looked down at the open refrigerator. Back up at her, "and beer," down and back up again, "and fucking meat." Guess that meant he was going to crash here for a while.
Despite his rather dense attempt at a joke, he could tell she was angry with him. He would be angry with him too if he was her. So Thor shut the refrigerator door, walked casually over to her and wrapped his arms around his mother's shoulders. "I'm an awful son, an even worse husband and a deadbeat father," he said as he hugged her. "And it's about time I came home, I just didn't know when I'd be ready so there was no way for me to tell you when I'd be coming home. Dangerous times or no, your home is always safer with me in it than with me not in it and you know this. I'm thinking about getting a dog."
Yes, that whole line of thought was smushed right together in way that made it seem like absolutely everything was connected.
