Some secrets about T'Pol's (Jolene Blalock) past will be revealed in the seventh episode of "Enterprise's" second season.

According to TrekWeb, the upcoming episode "The Seventh" will put the Enterprise crew in hunt of a fugitive from the Vulcan High Command.

The crew visits a planet where Vulcan intelligence believes this fugitive -- Menos -- is hiding. He's found in a bar and apprehended by the crew, but are stuck on the planet when they learn the landing pad their shuttlepod is on must be thermalized for several hours to remove a thick layer of xyalthoric acid.

T'Pol takes the opportunity to search Menos' ship, but finds nothing of substance. She then starts having flashbacks of a murder that not only Menos was involved in, but herself as well. The flashbacks also contain her going out of control in a Vulcan monastery, apparently as she is repressing the event.

A complete detail of the episode is available at TrekWeb.

Please note that none of this has been confirmed by Paramount Pictures and should be treated as any rumor would.
