Thomas Lockwood

 was a houseguest on Big Brother 1.

Thomas's journey was anything but smooth in the Big Brother House. Thomas' game was thought to have come to an end when he was evicted from the Big Brother House on Week 1, being the first ever person evicted. However, that all turned around when Thomas won the first battle back of the season, and came back at the end of Week 5. Thomas had some ground to catch up, including continuing to build his bond with William, but that ended when William was backdoored in Week 6. Thomas then took revenge when he nominated Mark and Robin in Week 7 after he won HoH, and Mark was successfully evicted. He then won HoH in Week 9, where he nominated Cris and Omid for never being nominated. He tried to evict Cris when Robin veto'ed Omid, but putting up Justin as a replacement ended up being a mistake, when Justin was evicted by a 4-0 vote. His game came to an end when Cris won both the HoH and PoV in Week 10 and evicted Thomas. Thomas was evicted in 7th place and became the 5th member of the jury.
