In the preview, Petra (Yael Grobglas) get Jane to admit that she's not "100 percent" over Rafael, just before Jane's shown disrobing and entering a bathroom that appears to have Rafael taking a shower in it.
Now, there are some perfectly rational explanations that might exist for this encounter:
Perhaps she was looking for her first love, Adam (Tyler Posey), who she seems to have rekindled an easy spark with? Is this cut-together footage of their past? Are we looking at some editing trickery that splices together two wholly unrelated clips for intrigue's sake?
However, given the continued interest — especially by Baldoni — in seeing Jane and Rafael reunite, this might be just a preview of the Jane-Rafa romance to come.
Jane the Virgin premieres Friday, Oct. 13 at 8/7c on the CW.
