Adolin, the theory that she was faking it with him is false to me, she tried to he what she thought he wanted but didn't know how to pull it off and it worked in her favor. There is an attraction to Kal but nothing more. She even talked kal intonseeing him in a better light.
I also don't see Kal being the type to take her away from adolin as they had a serious bromance happening and syl would would not be down for that either.
I think Kal and Jasnah make a good pairing better then kal and shallan for sure.
