Sierra has been mistaken for Trish Stratus so many times it makes her sick. Sierra first came on the scene in EMF to seek Revenge on an old schoolmate. That woman was Katrina "The Black Widow" Ikeda. Sierra made it very clear that she was not only into men, but women as well. Leading to many jokes about being a switch hitter. She found herself aligned with Angelus Archer and was even in a "Relationship" Of sorts with him. After splitting with Archer, Sierra went for the owner of The Extreme Measures Federation and since then has been happily together with him.
Sierra also has a long and drawn out feud with VP Amy Dumas now Amy Jericho. After causing Amy so much pain and distress Amy finally got the upper hand on Sierra and eventually the two put all differences aside and joined forces...Now the Very best of friends.
