The Young and the Restless character Sienna Bacall, played by Daytime Emmy-winner Tamara Braun, appears to be Matt Clark's victim, as much as Noah, Nick, and Sharon have been. But that doesn't mean Sharon's not going to want to have a chat with Mrs. Bacall. Braun is previewing Sienna and Sharon clearing the air when it comes to Sharon's son.
The Young and the Restless, Sienna and Noah's future

Sienna staying in Los Angeles truly wasn't an option given the true nature of her husband, Mitch AKA Matt Clark (Roger Howarth). "I think she didn't have much of a choice," Braun told Soap Opera Digest about her character making the move to Genoa City.
Sienna was hoping to find a short-term place where she would feel safe and figure out her next move. Her primary goal is to avoid Matt, who has nothing left to lose and is likely hellbent on getting even with his wife and the Newman clan! Sienna likely feels thankful to the Newmans for offering her a haven in this time of crisis.
So far, Sienna has likely felt a chilly reception from the Newmans, and it's not just because it's fall in Genoa City! Braun understands that Sharon's apprehension towards Sienna is founded in concern for her son. After all, not only does Sharon not truly know Sienna, but Sienna's an older woman! Sienna may not have meant to, but she has brought some challenges into Noah's (Lucas Adams).
Matt Clark may not be done yet

Had the two not been romantically involved, it's possible that Matt wouldn't have gone after Noah. Oh, sure, he would have used the young man as a pawn against his parents. But once Matt found out that his wife and Noah were involved, all bets were off when it came to Noah's safety! Sienna knows that she's not likely the first choice that Nick and Sharon would make when it comes to her son finding a woman to spend the rest of his life with.
Sienna's not only dealing with the threat of her husband coming to town and seeking revenge, but she's also getting an up-close look at the Newman lifestyle. She's getting a view of just how wealthy Noah's family is! Sienna's likely going to play down how impressed she is with the Newman fortune and lifestyle.
But how will she handle Sharon being a protective mama bear over Noah? Tune in to find out!
