Superman wasn't sure what to think. He had been surprised to find Lara live and in the flesh in his Fortress of Solitude. He was even more surprised when Lara revealed herself to be Loki, and most shocked to learn that this was supposedly no trick on the Super-villains part, but that the Liesmith really claimed to be Clark's biological mother. Clark was skeptical, but heard the other out as he explained the circumstances of his birth, why he was sent to Earth in a lifepod, and why Loki felt that he could not safely make contact with his son until now. It was a lot to take in, and Clark needed some time to come to grips with this revelation. Loki nodded his head sadly, saying that he hoped that they would be able to talk again sometime in the near future before vanishing in a puff of green smoke.
Clark wasn't sure if what he had heard could possibly be true. But there was perhaps one person who might be able to verify at least part of the story. They didn't often fight together, but of course everyone knew the location of the Avengers' tower in New York. Superman flew to their landing pad on the roof, and politely enquired if Thor was in residence. The Asgardian bounded outside a short time later, greeting Superman with a hearty hand shake and asking if he would like to spar. Superman declined, stating that he had come following a recent encounter with Loki. Thor looked concerned, and asked if his brother was alright. Reassured as to his brother's health, Thor then hoped that he had not caused the other hero too much trouble. Superman said no, and that he only wanted to clarify a few things that came up during the encounter. Thor looked grave when he found out the subject in question was Loki's children. He didn't go into much detail, but looked ashamed as he confirmed the sad fates that had befallen most of them. He said sadly that Odin had not always been the best father, and had treated Loki and his children too harshly. He lamented that he himself had not always been the best brother, and that if he had taken Loki's side back then his brother might never have fallen into his current wickedness.
Superman took Thor's belief that there was still good in Loki to heart. That it only needed someone to be able to reach him through his pain and despair to draw him back to the light. Loki had always been a bit of a troublemaker, but his truly destructive urges had come only after breaking when his life became too painful. Clark wanted to reach out to the other man, but wasn't sure how. Fortunately Martha came to his rescue, when she asked Clark to invite him for dinner. Clark had told her that he had reconnected with his birth mother. Martha had immediately wanted to meet the woman. Clark had hesitantly informed her that his mother was only sometimes a woman, and was most-times the male supervillain Loki. Martha had paused for only a moment before saying that she would still like to meet Clark's biological parent.
Loki was honored by Martha's invitation and dithered about trying to decide what to wear. At first he thought of going as Lara Jor-El, but finally decided it would be best if he went in his Aesir form. It might not be his natural form, but it was the one he was most used to and the one he often thought of as his true self, Jotun by birth or not. He wanted to honor Kal's adoptive mother by being as truthful with her as he could.
Although they had indoctrinated his son with their quaint human notions of morality, it was also clear that Kal's adoptive parents had provided the boy with love and care and sheltered and protected him from a world in which he was intrinsically different. Loki felt a pang wondering how his own life would have gone if he had been found by such parents.
He nervously followed his son up to the front door of the little yellow house, and was graciously welcomed inside by Mrs Kent. Martha thanked him for the flowers and wine he had brought as gifts, and asked him to take a seat at the table while she got the food. As they made small talk over dinner, Loki decided that he liked Martha —her gentle, caring nature hid a will of steel. She reminded Loki a lot of Frigga.
After dinner they retired to the living room, where the topic of conversation turned to one dear to the hearts of Loki and Martha—Clark. Loki laughed and Clark blushed as Martha told story after story of Clark's mishaps growing up. To his great embarrassment, she even brought out pictures from when he was a child.
Clark had always wondered why his biological parents had sent him away. Wondered if they had ever loved him. Meeting Jor-El's hologram had done little to sooth his doubts. The man had seemed clinical and detached and Clark wondered if Kryptonians were even capable of emotions. Loki was another story entirely. No one would ever call the trickster god calm or detached! Loki had earnestly assured Clark that he had loved and wanted him, and that only fear over what Clark's grandfather might do to him had kept him away all this time. Of course he might be lying, and all of this might be some trick or elaborate ruse to worm his way into Superman's confidence. But seeing his intensity as he slowly took in each picture in Clark's baby book, the way he softly stroked the lock of hair fastened to one page, and the way he soaked up all of Martha's stories of Clark when he was a child were all evidence that this was the real thing, that Loki had sought him out simply from a desire to see his son again. Eventually Loki returned the favor and all three of them had tears in their eyes as he quietly recounted the first time he had held Kal-El in his arms following his birth. Something eased in Clark's chest at this evidence that his birth mother had really wanted and loved him.
