In "902 - 100 '', Silver and Teddy have a dispute over the baby. Silver wants to completely erase Teddy out of the picture, but rightfully believes that 's unfair. A couple episodes later, when Teddy refuses to sign a form forfeiting all his parental rights, Silver goes to Teddy 's uncle who threatens to have the embryos frozen or destroyed. Furious with Silver, Teddy again refuses to sign over his parental rights but Silver forges his signature. Teddy then brings in Shane 's sister, Michaela (Lyndon Smith) from Washington, D.C. She agrees to become Silver 's surrogate. When Dixon discovers Michaela has an incredible singing voice he wants to sign her to his record label. But Silver does n't think that 's a good idea as she feels Michaela should not be doing anything strenuous. Meanwhile, Silver attempts to reconcile her friendship with Adrianna. As they do, Annie and Naomi 's half - brother Mark (Charlie Weber) arrives in LA and Silver and Ade make a pact to not let a guy come in between them. But then Silver finally confesses to Ade that she slept with Mark. Adrianna at first pretends she 's okay with it but when Silver leaves, she shows her anger. She accuses Silver of not having changed since high school and tells her she does n't want to be her friend anymore.
