The Young and the Restless: Tamara Braun debuts as Sienna

Badass Sienna, played by Tamara Braun in her debut on The Young and the Restless, is already on the fast track to becoming a fan favorite. Fans are already wondering how many of Audra and Holden's secrets she knows. The scenes today with Holden and Claire were a great introduction to Sienna, and it is easy to see she won’t have any problems rattling cages that need to be rattled. Holding her own is something it looks like she is simply born to do.
Fans have been quick to comment on her first scenes on the Soap Central Message Boards.
24Kasie76 was the first to comment —Love her already on the show. TB. But who has Holden hurt? Did Audra kill someone, or Holden, and or both? Sienna invokes the prison word today about Audra, and Holden seems SHADY as can be, sitting there and talking even more privately to Sienna. I have a BAD feeling that something awful is in his past on this. Sienna was making it appear that Holden did something really awful. I hope so. I do not trust him whatsoever, never have, so Claire is a big dummy trusting this loser to even go away with him and barely know this sneak.I never trusted Holden, not at all.

Valued Contributor Cloverleaf added –– So, if Holden and Audra were in LA together, where were they working? This must have been before Holden hooked up with Damian and started working for Cane. Do I have that right? What was Audra doing in LA? Was she working with Tucker at the time? Holden never worked for Tucker, as far as we know, so how did they meet? What were they doing together? I'm curious if we'll ever find out or if this will be one of those s/l's that is just a tease and then is never mentioned again.
Henyvo02 –– Well, we know Audra had been working for Tucker since she was very young, and Holden said he knew Tucker, so I would presume Audra was working for Tucker when they met
Regular Writer zenmaster5 said –– As henyvo02 mentioned, we know Audra was working for Tucker at the time, but Holden, I'm not sure...I thought some music guy tried to take advantage of Audra, and Holden helped her out of that situation...maybe Holden was involved in the music scene when he was in LA and did know Tucker! We know that Holden and Damien were best friends for the longest time, and Damien knew Audra, too, so they all had some kind of affiliation with Tucker in the music scene. I would love it if we knew the history as well, as it would help the story make sense with all the different players.
The Young and the Restless welcomes Tamara Braun and so do we, bring on the drama Sienna!
