Wesley Wyndham-Pryce was sent to Sunnydale as the replacement Watcher when Giles was fired. He had little control over Buffy and lost Faith completely to the Mayor's team. His Watcher's technique is somewhat bumbling; his capturing of Faith was marred slightly by her escape, and Buffy quit the Council while under his control. Quite often he had little to contribute to the gang (his specialty being whimpering when wounded and screaming like a woman) but his intentions were always honorable. He enjoyed a brief flirtation with Cordelia but there were no sparks when they eventually kissed. After defeating the Mayor-Snake, he was fired from the Watcher's Council and took up as a "Rogue Demon Hunter", swapping his Watcher's suits for Biker's leather. He eventually found himself in LA with Angel and Cordelia, where his sincerity, enthusiasm to help and considerable research skills won him a place at Angel Investigations where he helps fight the good fight. His past is fuzzy; he appears to have had a domineering father who locked him under the stairs for hours on end and it would appear that Wesley is trying to make him proud of who he has become… with little success, even though he eventually became the boss of Angel investigations.

Alexis Denisof, 58, was born to the son of Russian immigrants; his mother was born in Philadelphia. He grew up in Seattle with his mother and was then sent to New Hampshire to attend boarding school. He traveled through Europe after finishing high school and finally settled in London to join the London Academy of Music and Dramatic Arts and then the Royal Shakespeare Company. While acting in theatre in England he met Anthony Stewart Head in a production of Rope. A few years later he returned to the US with friends to nurse a broken heart, and wound up filming a pilot which never came to fruition. He was then involved in projects including the TV miniseries Noah's Ark, First Knight, and an episode of Highlander. He finally landed the role of Wesley due to ASH suggesting him for the role. His character was originally intended to be killed after two episodes, but Alexis has since crossed over to become a regular in the spin-off series Angel.
