Eureka: Season 2, Episode 7

2 - 7: Family Reunion

Fargo's grandfather, Pierre Fargo, is revived from cryogenic suspension in an unmarked sleeper pod at Global Dynamics. Once awake, he accuses his old rival of locking him in the pod, and stealing his life's work. It's found that the scientist did steal his work, but Pierre's best friend locked him up. He was locked up because his best friend was in love with Pierre's fiancee (Fargo's grandmother), so he froze Pierre. Pierre then ages and looks like a regular grandpa.
