In the script's first draft, The Android kisses Victor. In the second draft, Victor kisses The Android. In the third and final draft, Victor asks The Android if he can kiss her before kissing her. Just kiss the girl already!
The reveal of young Tanner was achieved by visual effects supervisor Lawren Bancroft-Wilson, who gave Tanner a CG facelift and 'borrowed' supervising producer Ivon Bartok's hairline to give him a more youthful appearance. TV magic!
