I don't know if it's solely in the movies but I think Sharon Carter is Peggy's granddaughter in the movies, and I think it's weird that Sharon is Steve's love interest. I mean it's weird right? That he would date Sharon given her relation to Peggy and to date Steve I think is weird. Maybe it's because I liked Widow and Cap in the Avengers Animated Movies but I just don't feel like Sharon and Steve really fit in MCU (they feel forced) though my preference might also be do to the fact that Scarlet and Chris have worked a lot together in the past and because of that they work very well together.
