I was summoned?
It was not long during this conversation had Thor left the household. Massive and mighty, carrying weights with him to lift in the yard as he sometimes was want to do. He was dressed in a tank top of human make, one that stretched and poured over his every muscle, and a pair of comfortable pants fit for athletics. He had remembered the few fashion pieces he learned from his time on Earth, when not trying to choose for himself--hoods, he recalled, were not not-suspicious.
And quietly he listened to the conversation round the bend until, in his agitation despite his glorious battle only mere days prior, he dropped his massive weights. They hit the ground like leaden thuds leaving marks in the grass and dirt from their heft. Thor left his station to come around, perhaps a bit to Katherine's defenses, and perhaps to put the young human in his place.
"There will be no way back," he said in that rumbling voice. "My niece is quite right. Many have tried, including myself...all have failed. If they leave it is because they have fallen to their deaths or this place has grown weary of their games." In his own upset at the situation, the god looked more menacing in his anger than normal--most might even consider him jovial most of the time, but not today. Not as of late.
"Katherine, is he bothering you?" the blond finally asked in a more hushed, private style of tone, though he was not very good at subtle. He could definitely be overheard.
