'UnREAL' season finale spoilers, plot news: Everlasting's first villain follows cast in London

What is Britney (Arielle Kebbel) doing in London during the final episode of 'UnREAL'Lifetime

Most of the current real-world dating shows on TV have highly controversial endings, and it seems like the finale for "Everlasting" will be like the rest of them when "UnREAL" wraps up its first season. 

"Everlasting's" charming suitor Adam Cromwell (Freddie Stroma) will bring the remaining contestants to London to visit his hometown where he will choose who among them will receive a proposal from him. Does this mean that Quinn King (Constance Zimmer) has persuaded Adam to continue doing reality TV? Fans will recall that King threatened Adam of releasing his sex footage with Rachel Goldberg (Shiri Appleby) if he will not agree to have an onscreen wedding and a spin-off series featuring his life with the "Everlasting" winner after the reality show's first season. 

Based on the trailer for "UnREAL's" 10th episode offering titled "Future," the reality show contestants are preparing for a the big TV wedding that will be shot in the U.K., and they even meet his ultra-rich family. They also try on some wedding dresses until Britney (Arielle Kebbel) arrives in town to steal the show. 

Britney was the very first contestant that was eliminated in the reality dating competition, and she was the first villainous character that was featured in the show. It seems like series creator Chet Wilton (Craig Bierko) wants to add another element to "Everlasting's" finale, which is why he asked Britney to return to the show. 

But Britney's sudden appearance is not the only drama seen in the season finale trailer. In one of the scenes, cameraman Jeremy (Josh Kelly) proposes to Rachel in front of national TV. He broke up with the show's makeup artist Lizzie (Siobhan Williams) to reunite with his former girlfriend. However, it is unclear if Rachel is going to accept his proposal since they only got back together recently after she slept with Adam. How will Adam react to this? 

"UnREAL's" first season finale is slated to air on Monday, August 3, on Lifetime Network.
