Frigga and Thor.
Thor recounted his meeting with Loki when he first arrived on the station. Meeting Kat and meeting Zu. Loki hadn't told him a great deal. He had especially left out things about their future. Thor was unaware of Loki's condition among other things.
"As for home" he replied. He paused and shook his head. "We lost you..." he said, his voice quivering just ever so slightly. "I never thought I would see you again. When I first heard you were here, I refused to believe it. I thought it was another trick, but I did not understand the deception. Then I came to realise it was true" he said, looking to her.
