There will be a shocking twist in the next all-new episode of "Jane The Virgin" on Monday, March 9.

In the last episode, "Chapter 14," Rafael and Jane realized that despite the growth in their relationship, they have yet to gain mutual trust, notes Entertainment Weekly. They also reached a new pinnacle in their relationship when they told each other that they loved one another.

At the beginning of the episode, Michael dropped a bomb when he announced to Jane and Rafael that Rose is really notorious drug dealer Sin Rostro. Michael also asked Rafael to notify him if he hears from Emilio, who was buried alive with concrete.

In addition to the many fans who were surprised to learn that Rose is Sin Rostro, actress Bridget Regan admitted that she, too, was shocked by the revelation.

"I really thought I was this former lawyer/trophy wife who's now an interior decorator for her husband's chain of hotels. I was playing into that," Regan told E! News. "The only note [showrunner] Jennie [Urman] gave me when we started was that my feelings for Luisa were 100 percent real. As the season progressed, I started to get these little tiny hints in the script and I started to suspect that Rose has ulterior motives. And then Jennie told me and I read 'Chapter 12' and I just about died. I was so thrilled!" she added.

In the next episode, "Chapter Fifteen," Alba's relationship advice to Jane and Xo will result in them having unexpected friction with Rafael and Rogelio. Meanwhile, Petra finds herself with an unexpected ally, and Jane will become determined to get her favorite literary idol to read her book, reports Ksite TV.

The executive producer also dropped hints about Jane and Michael relationship.

"There are a few moments where Michael helps Jane with certain things that he knows how to help her with only because of their history, and that starts to play a big part in their reconnection. At the same time, her relationship with Rafael gets stressed the more they start to think about the practicals of what their life will be and what their life will look like together," said Urman, reports TVLine.

A preview of the upcoming episode reveals that Rafael will propose to Jane.

According to Kpop Starz, the synopsis for "Jane the Virgin" chapter 15 reads as follows: "When Jane (Gina Rodriguez) and Rafael (Justin Baldoni) receive news about their baby's health, they revisit moving in together which prompts a surprise from Rafael."

Season 1, Episode 15 of "Jane The Virgin," entitled "Chapter 15" will air on Monday, March 9, on The CW.
