For all that it was a bit condescending, Loki's smile was genuinely fond as he followed the overexcited thunder god's progression through the apartment. It was easy to forget that there were monsters waiting for them outside and be lost in the wonder of the box that told stories with bits of light, or the intricate cleanliness of the cooking space. When they discovered the hot running water, all bets were off. Thor determined that the only thing to do was see if he could outlast the heat in a battle of the shower, and Loki went to amuse himself elsewhere. By the time he came back, his friend had emerged wrinkled and red from the heat of the water. That was when they decided to investigate the hot water heater.
And so it went for the rest of the day. When they had thoroughly "investigated" (read, trashed) the entirety of James' apartment, they moved on to bigger and better things. When the sheer exhaustion of maintaining a presence in their mortal form caught up with them, they had the hood open on James' car and were poking around to see what made it tick. The physical crash was probably all that prevented a much more violent end to the day.
As it was, Richard woke up with a splitting headache and a strange taste in his mouth halfway through November 1st, sprawled over the back seat of James' car. Not sure what had happened, or exactly whose car it was, he crawled back up into his room and slept until the headache went away.
