From The Stargate Omnipedia
Timothy Harlowe
Top geneticist with full security clearance, summoned to the
S.G.C. to examine
Teal'c after he has been infected by an alien insect from
BP6-3Q1. Called "Timothy" by friends, he worked alongside
Samantha Carter during her time at the Pentagon. He deduced that Teal'c was undergoing a transformation and that in the end he would become a multitude of the insects.
Timothy was thrilled to be able to examine an alien, and had a plan to use RNA inhibitors, combined with Teal'c's helpful symbiote, to cure him. Unfortunately he was intercepted by Colonel Maybourne who encouraged him to put Teal'c under his care. Timothy was not aware Teal'c would be put away to allow the transformation to run its course. After Teal'c was gone, he realized he had betrayed Carter's trust.
Fortunately, Teal'c was located in an abandoned building in Colorado Springs and returned to the S.G.C. in time to administer treatment.
