There will be lots in store during the rest of Season 1 of "Jane The Virgin," including another story twist around Sin Rostro.

In the last episode, "Chapter Fourteen," Michael dropped a bomb when he announced to Jane and Rafael that Rose is really the notorious drug dealer who goes by the alias Sin Rostro. Although it came as a complete shock to fans, showrunner Jennie Snyder Urman admitted that she planned the surprising twist when she first began writing the script.

"This was our plan from our first week in the writers' room, when we got together and were trying to figure out what the crime would be that was going on in the hotel that led to the surveillance of that in the first place," Urman told Vulture. "This was something that we planned from the get-go and then next week's episode we go back through all of the clues that were laid in along the way."

The executive producer also dropped hints about another character like Sin Rostro who will be introduced on the show.

"By the end of the season, there'll be another Sin Rostro-esque twist, something that's more soapy and telenovela-y, and you'll see it's all to the same end, but I think then it twists back on itself unexpectedly. Which is a very cryptic way of saying we like to go one way and go really far and deep into the telenovela and then bring it back around to more personal and quirky moments, because even Sin Rostro has feelings."

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 gave hints about Jane and Michael's 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.

According to Kpop Starz, the synopsis for "Jane the Virgin" Episode 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 Fifteen" will air on Monday, March 9, on The CW.
