When Tess awakened at Cadmus Labs, she found the young clone who went by the name "Alexander". She asked who the other people were and Alexander replied that they were his "brothers". While he wasn't paying attention, Tess released an older clone. She told Alexander to run away, which he did. Later at the Luthor Mansion, Alexander played with some old soldier toys, while Tess gave him a glass of milk. Unknown to Tess, Alexander had placed one of the toys within the nearby fireplace prior to her arrival.
When Tess discovered that Alexander's intellect was far superior than that of the average child, she planned to send him away for further testing and also learned that he was aging abnormally fast. However after joining forces with Clark Kent and Oliver Queen and taking up the mantle of Watchtower from the missing Chloe Sullivan, she reconsidered and decided that what Alexander needed was love. Upon taking advice from Cat Grant, Tess read Peter Pan to Alexander. He then told her that he loved her, to which Tess began to cry, as she had never been truly loved by anyone and continued to read the story.
As much as Tess devoted herself to prevent Alexander from falling off a righteous path that she was on, to be better than Lex Luthor was or what he used to be, it seemed inevitable that he return to his true nature. Tess gave Alexander a "birthday party" with many young children to celebrate with him, and as he was enjoying it, he started drawing on a paper plate the House of El emblem. With that stroke of memory, Alexander had a seizure which Tess and the therapist ran to his aid. Stealing a key from Tess, he ran from the mansion to find out where his memories were connected to for he believed that the Wearer of the El Symbol was evil and wanted to kill him. Alexander started remembering the times Lex spent in the Kent Farm with Clark (recalling when Lex told Clark that their friendship would be the "thing of legend" and when Lex tied Clark's bowtie), as he looked through the pictures in the book. Tess managed to find him, however she realized that she was too late, as not only did Alexander remember Lex's past but also the emotions that came along with them when Clark and Lex drifted away from each other. Tess continued to reach out to him, but he drifted away believing that she only wanted to help so she could redeem herself from her evil deeds that she committed. And once Alexander struck a nerve about the powerful men in her life (Lex, Oliver, Zod and Clark), Tess struck him. And for that, Alexander refused her help for good. After drawing the House of El emblem in several papers, Alexander had shaved his head and changed his clothes to a purple and black attire, redeeming Lex's trademark bald-headed figure and attire with a demented smirk on his face.
Weeks later, Tess had moved Alexander to a locked room in Cadmus Labs. He had continued to draw the House of El symbol but had escaped, only leaving behind a book Tess had read to him, stating that he was "all grown up now", much to the horror of Clark and Tess. Tess did some more tests on Alexander after an incident with a hypodermic needle and discovered that he is actually created from half of Clark's DNA as well as Lex's DNA and now dubbed "Conner". She took him to see Clark in hopes that he would act as a mentor to their "brother".
Although Conner eventually went away from Smallville and lived under his new identity as a member of the Kent Family, Tess took extra measures to hide him from Lionel Luthor. This proved most fortunate as Lionel had discovered Lex's composite clone body, which was only missing a heart, which Lionel had intended to take from Conner for Lex but couldn't due to Tess's actions.
