Warning: spoilers for Prime Video’s Cruel Intentions TV show.
TheCruel IntentionsTV show made big changes to the 1999 movie’s characters while borrowing its premise, and as such, it gave a completely new ending to Lucien (Zac Burgess), in which he had one final move against his step-sister, Caroline (Sarah Catherine Hook). Based on the 1999 movie by Roger Krumble and the 1782 novelLes Liaisons Dangereuses, by Pierre Choderlos de Laclos,Cruel Intentionstook viewers to a Washington D.C. college where its wealthy students stop at nothing to get what they want and always for their own benefit.
Cruel Intentionsfollowed step-siblings Caroline and Lucien, who made a bet Caroline came up with to save her fraternity: Lucien had to seduce and sleep with the Vice President’s daughter, Annie Grover (Savannah Lee Smith), so they could convince her to join Delta Phi, of which Caroline was President. However, Lucien developed feelings for Annie and called off the bet even though he slept with Annie – but as for Caroline he failed, she released Lucien’s sex tapes. To her surprise, Lucien had one final move against her, and he shared with her one more video on their shared file.

Lucien Shared His Video With Caroline’s Mom At The End Of Cruel Intentions’ TV Show
Lucien Shared A Very Specific Video With Caroline
In addition to seducing and sleeping with many students and more,Lucien had a habit of videotaping his sexual encounters. Annie was no exception, but he promised her that no one would ever see that tape. Lucien used to upload his sex tapes to a shared file with Caroline, but he kept his word and didn’t show her his tape with Annie – in fact, he didn’t even tell Caroline that he slept with Annie. After Caroline released his sex tapes, Lucien knew exactly what to do next, so he paid a visit to his stepmother a.k.a. Caroline’s mother.
Lucien had sex with Caroline’s mother and recorded the whole thing, and that’s the file he shared with Caroline.

It was shown in the first episode ofCruel Intentionsthat Caroline’s mother was attracted to Lucien, and she continued to show her predilection for her stepson later on in the show, so Lucien took advantage of this. Lucien had sex with Caroline’s mother and recorded the whole thing, and that’s the file he shared with Caroline atthe end ofCruel Intentions.
Although Annie’s tape is also a candidate, more so as he also got a call from her in the final minutes of season 1, Lucien has feelings for Annie and kept his word of not showing her tape to anyone. As Lucien wanted to get back at Caroline, it makes more sense that he shared his stepmother’s video, especially after their last conversation.

Lucien Knows How To Get To Caroline
After finding Caroline with Professor Chadwick (Sean Patrick Thomas), Lucien confronted her about the bet. Lucien withdrew from it and told her he now understood why her mother never loved her, which further angered Caroline and motivated her to release his sex tapes.Lucien knew well how Caroline’s bad relationship with her mother deeply affected her, even seeing her break down at dinner with her mother. Lucien also knew how cruel Caroline could be, so he decided to get back at her by playing her own game.
By sharing his sex tape with Caroline’s mom with Caroline,Lucien was further proving to Caroline that he’s the one her mother cares about, not her, and that he can also play dirty as she does. IfCruel Intentionsgets a second season, the aftermath of Lucien’s sex tape with his stepmother will surely be addressed, as well as how it will affect his once close relationship with Caroline, which is now shattered after what both of them did.
