In Season 2, Episode 3, future Sophie tells her son that before she turned 40, she had kissed all of her friends, sending the "How I Met Your Father" fanbase into a spiral. She doesn't clarify to what degree any of these kisses were, so some will more-than-likely end up being nothing more than a peck, but some fans quickly wondered what this could mean for Sophie and Sid.
Arguably the biggest Sophie and Sid shipper, @stevenrogered, has a Twitter thread dating back to February 2022, piecing together the clues that the characters end up together. While they recognize future Sophie's comments mean she kisses everyone, they refuse to focus on anything but a potential relationship with Sid. "We get confirmation that they kiss at some point," they wrote in all caps. "And that she also kisses Valentina, Ellen, and Charlie, but SidSophie has a kiss coming." Other fans, like @leighslilsis, @scenophile, and @gingerneighbor, echoed this sentiment, showing that they couldn't be happier to know that a Sid and Sophie kiss is on the way. @Karrywood123 expressed various emotions, saying, "Omg, so this means Sid & Sophie are going to kiss, but then so are Sophie & Charlie." @AmandaJ718 is doing some detective work of their own, wondering if Sophie's kid sounds like Sid to anyone else, while @ashyxzc plainly states, "Sid and Sophie endgame is where it's at."
While there weren't as many Sid and Sophie shippers on Reddit, fans couldn't help but wonder what future Sophie's comments meant for Sid's current relationship. U/No-Childhood6608 and u/florentinsch think doom is on the way for Sid and Hannah's marriage, allowing Sophie and Sid to explore what the fans want them to.
