Captain America hasn't had much luck with romance since he awakened in the present day, whether it's because he's been busy with Avengers or S.H.I.E.L.D. missions, is still catching up on how things have changed since the 1940s or he just hasn't found anyone who's caught his fancy. However, one woman Steve Rogers has had a few sparks with in the modern era is former S.H.I.E.L.D. operative-turned-CIA agent Sharon Carter. Introduced in Captain America: The Winter Soldier, Sharon helped Steve again during Captain America: Civil War, but there's been no word on if/when Sharon will return to the Marvel Cinematic Universe. When asked about her future with the franchise, Emily VanCamp said that's still to be determined, adding:
Marvel can call at any minute.
While plugging her upcoming TV series The Resident at the Television Critics Association press tour (via Deadline), Emily VanCamp was questioned about what the future holds in store for her version of Sharon Carter, and as of right now, it's up in the air. Given that Steve and Sharon finally seemed to hit it off romantically during Captain America: Civil War, as evidenced by them kissing shortly before the movie's airport battle, one would think that we might revisit the two of them together at some point. However, Avengers: Infinity War wrapped up its production last summer, and Avengers 4 is almost finished rolling cameras, with several of the movie's main actors having already departed. So unless VanCamp is intentionally keeping some kind of cameo to herself or Marvel calls her at the last minute, it doesn't sound like we'll see Sharon again before Phase Three concludes.
Although Peggy Carter has arguably become Captain America's most well-known love interest, in the comics, Sharon and Steve have been more closely intertwined. Sharon was initially introduced as Peggy's younger sister, but as the years passed, she was retconned to being Peggy's great niece, as is the case in the MCU. While the comics Sharon and Steve have gone on numerous adventures together over the course of their on-and-off romance, their film counterparts haven't spent too much time together, although they're interested in one another romantically. While it's certainly possible that Emily VanCamp could be called back for an appearance in Phase Four, given that Chris Evans' future with the MCU post-Avengers 4 is shrouded in mystery, it's hard to say if we'll ever see the two of them together again on the silver screen.
