As the room flickered quicker and quicker while it decided how to make them run screaming in abject terror over their worst nightmares coming true, their connection strengthened. Strange felt... everything. Exactly like he said. He felt everything all at once in a cacophanous roar of rejection, humiliation, longing, desire for love and respect and power and the need to protect. The problem was, he was still human. Strong and powerful of his own merits but human nonetheless. He wasn't sure if the fortifications in his mind were strong enough to stand the barrage he was putting them through.
But Loki was a God. Ancient, alien, genetically powerful. "Yes." Strange replied, grateful for him to focus on that part of Strange's own mind. "God, I loved her."
He felt his own love for Christine - along with his regrets - pour back at him in a loop with Loki's own understanding. Strange's hand shook in its grip of Loki's arm, desperately clinging to that love he felt. It had been good, it'd be sweet and pure, once. Strange focussed hard on Christine - the glint in her eyes when they'd play poker with candy in the breakroom, when she'd always outsmart him when nobody else was around, her unfailing charm and ease with people (the one thing he could never have). It was only her.
