Beware of unmarked spoilers!
Pair the Spares (although to what extent Jane/Raf/Petra can be considered a triangle is...debatable) is pretty common in soaps, and Jane the Virgin will lampoon this by having Michael and Petra spend some quality time together...but it will be humorously unsatisfying for both.
- Jossed, but Chapter Eighty-Two did suggest his brainwashed persona Jason had the hots for her.
At the end of Chapter 11, Michael told Xiomara that he was still in love with Jane and that he'd never give up hope that they'd eventually get back together, after which the narrator says that Michael wholeheartedly believed this until the day he died. This could be foreshadowing Michael's impending death which, one can guess, will be in the not too distant future, given that by that time he still won't be over Jane.
- As of Chapter 54, confirmed.
But will be brought back by Hollywood Science / telenovela magic (eg. Magical Defibrillator, CPR: Clean, Pretty, Reliable, etc., any way he can be declared functionally dead before being brought back at the last minute). This way, his character won't be tied down by the narrator's promise to always love Jane should the writers decide to go in a different direction. Obviously, the telenovela cheesiness of this trope will be lampshaded.
- Alternatively he'll go into a Coma for an extended period of time, a common telenovela trope, and this will be lampshaded
- Jossed, Until "Chapter Eighty-One", where he is seemingly alive.
- Magda's secret
- Magda killed Ivan because the secret Magda had could make Petra never forgive her. Maybe Magda knows Petra wouldn't forgive her if she knew Magda was lying about her being an only child, especially if Magda got rid of Petra's twin for a selfish reason. Petra forgave her mother for pretending to be paralyzed for years, so it would have to be a pretty terrible secret.
- Twin's run in the family
- During Petra's ultrasound, the OBGYN asked Petra if twins ran in her family, which Petra quickly says no to. This could be the writers' way of foreshadowing that twins do run in the family as Petra was actually one herself.
- Magda's comments on Petra being too big in the middle already
- After Magda is released from prison, Magda says that Petra is too big around the middle. Petra quickly reminds her mother that she is having twins, which Magda replies that her middle is still too big anyway. This does fit Magda's personality, but it she might also have this opinion from her own experience carrying twins.
- As of Chapter 39, confirmed. Chapter 100 reveals Petra and Anezka are two members of a set of triplets.
They went to the trouble of casting a very attractive actor in this role, and he doesn't look much older than her (all though the actor is quite a bit older than Gina Rodriguez in real life). Jane started out disliking him but he was never actually all that unreasonable, and his advice is actually helpful to her as a writer - and the winter finale showed that he will look out for her and stand up for her if she actually tells him what she needs. It would be a really interesting relationship if only because it would develop in the opposite direction as her relationship with Michael and Raf - instead of starting out thinking he hung the moon and being disillusioned, she'd slowly be learning to value a person she initially disliked. And of course the fact it's probably kind of inappropriate for an advisor to date their advisee could only fuel the telenovela drama goodness.
- As of Chapter 33, confirmed.
- Considering how pale skinned they are I think that's safely jossed.
- Seconded. Word of God has said that the Lemony Narrator is highly connected to the Villanueva family and simply hasn't been "outed" yet. He would have natural storytelling talent from Alba (as seen, the girl can write when she wants to!), Xiomara (singers tell stories, just through music), Rogelio as an actor, and Jane the writer herself. He would know all the details, with Alba and Xo telling him stories at their knee and Rogelio acting it all out to please him (because you know Rogelio would do a one-man-show on this for his favorite audience of one). He'd know the stories. All of them. And with way too many details if he just asks multiple people.
- Confirmed!
- Jossed.
- Jossed.
- As of Chapter 82, confirmed.
- Jossed, but with elements of truth. He definitely is Michael but Rose and her team did kidnap and brainwash him into thinking he was somebody else. She used another agent instead to spy on Luisa and her family
- This could mean the Narrator could be any of the above guesses in-universe, but filtered through Jane's writing.
- Confirmed as of Chapter One Hundred; the episode implies that Mateo is the narrator in a future retelling.
- The former — confirmed as of Chapter One Hundred
- Jossed as of Chapter One Hundred
- Jossed, JR shot Milos
- Confirmed in Chapter Ninety-Eight after Luisa pushes Rose off a roof onto a statue of Rogelio, however this wasn't a Heroic Sacrifice - Luisa comfortably remains on the roof.
