Noah was a vampire who became obsessed with Elena due to her being physically identical to Katherine. He unsuccessfully attacked Elena on several occasions, including causing her to flip her car while she was driving. There is a possibility that he could have been the guard that let Katherine go, because the church guard was also obsessed with her. How Noah happened to know Katherine is unknown, but when he asked the Salvatore brothers if they remembered him from somewhere, they seemed unsure.

Noah had got his official invite into Elena's house by acting like a pizza man. He tried to attack her the day after, but Elena was saved by Stefan. Noah was working with vampires, Anna and Ben, to open the tomb to help save the 26 vampires that were locked inside, before he was staked by Stefan. Before he was killed he told Damon and Stefan the info needed to find Emily's Grimoire, that it's in Johnathan Gilbert's journals.
