"She looks relatively unscathed," Loki promised Thor quickly, failing to cackle. Part of that might, in fact, be due to Sif's infusion of Cold Logic. Hard to tell. Sif got, in fact, a mildly apologetic look – whether or not Thor wasn't the one who deserved it – and Loki finally went back to standing on the floor like a sane human being just in time to collect Jotnar's leash. (And reassure the dog that, of course, he still liked him best.)
"Up until I was eight, Thor and his parents were my family," he asided to Sif quickly. "That's when my dad and Tyra came to find me again, of course." And that left out all the upset and arguments. Obviously.
