Studying – for one thing.
Thomas, whose legal name is Jonathan Weiss, attended Harvard University from 2000-2002 (he spent one semester abroad in Scotland) and graduated from Columbia University in 2010, where he went by the name Jonathan Weiss. In class, recalls a fellow student, "He loved to talk. He'd say really intelligent things."
He also filmed TV guest spots on Veronica Mars and 8 Simple Rules but has stayed largely out of the public eye and hasn't appeared on camera since 2005.
Thomas, who currently lives in the Los Angeles area, recently reunited with his Home Improvement cast at a photo shoot for Entertainment Weekly (see picture above). Patricia Richardson, who played his mother Jill on the hit show, Tweeted an update about her onscreen son and a photo of the reunited cast, writing, "Jonathan is acting, and he wants to direct!"
Surely, his fans will welcome him back!
