Sarah provides tech support for Telstar.
When Klaus decides to set up a home office in his alcove in "Epic Powder Dump", he finds his landline telephone wasn't connected. He angrily calls Telstar to complain, but when he reaches Sarah who has problems over her own, his anger turns to sympathy. Just as he begins to become attracted to her, his attempt to switch her off of speakerphone causes him to lose the connection. His attempts to locate her again are repeatedly blocked, but when he hears Snot in the house using Steve's computer, The latter volunteers to use his skills in tracking people down to help him locate her.
Based on the limited number of locations where his phone could ring, as well as the weather in the sounds of a train whistle, they narrow her location down to Roanoke, Virginia, but when Klaus visits, he finds that no one is home and chalks it up as a romance that was never meant to be, unaware that inside her house, there are similar charts to his home in Langley Falls, where she also knocks on the Smiths' door without result, and has to give up on him.
