Which would mean Jack knew Tiffany was pregnant before he left Chicago (since Gwen claims mom said she told Jack & he did nothing) Seems to me after Jack arrived in Salem....he fell for Kayla, was ill, she married him, Steve donated a kidney to him, Jack learned of Steve's & Kayla's love for each other, (I also remember Harper poisoning Kayla, so she was ill) but Jack finally demanded the consummation of their marriage which Kayla had been putting off, making excuses.....thus the rape, his long repentance for it, meeting Jen, etc. etc. It was a several years. And if he was married, had a child, then Gwen would have had to be 7-8 years old or more. Oh, well, Days pays no attention to timelines anyway, do they?
