Biography:

Savannah Weaver is the daughter of Catherine and Lachlan Weaver. Catherine was the CEO of the Zeira Corporation. Catherine and Lachlan died when Savannah was very young and a T-1001 subsequently stole Catherine's identity. Due to the T-1001's difficulties to obtain a normal relationship with Savannah, and thus maintain its cover, psychiatrist Boyd Sherman was consulted. On the anniversary of Lachlan's death, Catherine Weaver didn't recognize the emotional needs of her daughter, and left her on her regular daily schedule. After a conversation with James Ellison, who described how he dealt with his own father's death, Weaver recognized that it was important to bond over grief, and had Savannah brought to her office. Seeing Savannah crying, Weaver tried to sympathize with her, using Ellison's own story as her own, as a way to try to relate in grief. Eventually, Savannah is convinced to sit on Weaver's lap, realizing that her lap is cold. Weaver's attempts to demonstrate further human emotions were not entirely successful but were a gradual step toward building a bond with her daughter.
