The Tuesday, Oct. 14, episode of the CBS soap is set to introduce Emmy winner Tamara Braun as Sienna Bacall. Who is she? What does she want? Read on, and we’ll tell you all we know as you peruse gorgeous first-look photos of the actress in action.

In case you’ve been living under a rock for the last 20 years and are unaware of why Braun’s casting is such a big deal — and an exciting

 

 

development for Young & Restless — allow us to explain: Back in 2001, she did the impossible, not only replacing fan favorite Sarah Joy Brown as Carly Spencer on General Hospital but making the role of Sonny Corinthos’ moll entirely her own.

 

 

We’re all just assuming that L.A. nightclub owner Sienna is straight. But she could turn out to be yet another spoiler for troubled marrieds Mariah Copeland and Tessa Porter — which would be hella ironic, considering that on All My Children, the 2009 “I dos” of Braun’s Reese Williams and Eden Riegel’s Bianca Montgomery marked daytime’s first-ever same-sex wedding.

 

 

 

Sienna could actually bring to the table a love interest of her own, we just don’t know it yet. In fact, Young & Restless could be planning to reunite Braun with one of her former leading man. Which one?

Since Howarth is also joining Young & Restless, perhaps as a part of the mystery Braun as said is swirling around Sienna, their characters could have been involved… or could be about to be. The show has yet to disclose who he’s playing, even!

In these shots, she will. But you know, by and large, not so much. Anyway, there’s another character with whom Sienna is all but guaranteed to interact.

Sienna is in L.A., and so is Nick and Sharon Newman’s son, Noah. You don’t have to be a math whiz to add two and two and come up with the likelihood of them crossing paths. Fun fact: Since Noah has been recast with Days Our Lives‘ former Tripp Johnson, Lucas Adams, Young & Restless is staging a mother/son reunion. Braun won the first of her Emmys for her work as Tripp’s mercurial mom Ava Vitali on the Peacock soap.

It will be interesting to see how Sienna manages to get from L.A. to Genoa City. Since Noah is also a club empresario, perhaps he’ll team up with her to open the disco for which Wisconsin has just been begging. Can you imagine Victor Newman getting his groove on? (Don’t laugh; Eric Braeden’s got moves.)

Sienna is said to have “personal connections to several characters” on Young & Restless. Since both Audra Charles and Holden Novak have spent time in the City of Angels, we’d put money on them being at least two of ’em.

Heck, Sienna’s introduction may well shed some light at last on whatever shady business Audra and Holden got up to back when they were chilling in L.A.

… it’s pretty clever of Young & Restless to accessorize Sienna with a tie right from the get-go. Sartorially, she’ll fit right in with Genoa City’s old boys club.

Mind you, our hope is that Sienna will help Young & Restless break out of its lather, rinse, repeat cycle of business storylines with no real consequences. (We along with most viewers have, er, strong feelings on the subject.)

Braun won her second Daytime Emmy for Outstanding Supporting Actress for her portrayal of Kim on General Hospital. But it would appear that Sienna is cut from a very different cloth. Love the funky vibe!
