With a bittersweet end and a pinch of suspense, 'This Is Us' wrapped up Season 4. From Randall Pearson (Sterling K Brown) and Kevin Pearson's (Justin Hartley) big fight to the mysterious new faces, there's a lot to look forward to when the new season drops. 

While all the puzzle pieces from the past, present and future seem to fit in, the biggest mystery that remains to be solved is: Who is the man with a horse and a young brunette woman working at an art gallery? Struggling to tame a horse named George, a young man (Josh Hamilton) is seen with his little daughter. In the next scene, his daughter, Sadie (Glory Rose), tames the horse and scolds him for giving up on it too soon.

Cut to the next scene where we see the man heading to work. He is Eli, an OB/GYN, who visits his patient — and it turns out to be... Madison (Caitlin Thompson). She is pregnant and says she there's no one she wants to tell, as she can’t reveal it to her best friend and her baby's father doesn't know about it. Moreover, she is worried that this unplanned pregnancy will come a big blow to him. Repeating Sadie’s words, the doctor suggests Madison give the father a chance.

And then there's the woman at the art gallery, played by Adelaide Kane. In a flash-forward, she comes beside Jack Damon and his wife Lucy when they give birth to their baby girl, Hope. If we pick up hints from Kate and Toby's conversation, she is Jack's adopted sister, Hailey.

Talking about the new faces on the show, Dan Fogelman told The Hollywood Reporter, "We really love the actress we found to play the daughter, Adelaide, and obviously we've really [fallen in love with] Blake, who plays Jack Jr. So our hope is to continue to make people invested in these future storylines by getting into the characters slowly, as we've done, so that by the time you're really landing in full stories with them. If we do, you feel that great investment."

Pointing to Madison's doctor, Eli, he added, "Josh is a favorite actor of mine. The doctor becomes an important character next season to Kevin - he’s having twins with a virtual stranger, not a normal birth experience. It’s no coincidence he was introduced in the same episode that Dr K returned."

While Fogelman gives no clear hints, many fans are wondering if he could be Rebecca and Jack's dead child, Kyle, in a "what if" moment. "Calling it rn: the man with the horse is Kyle if he didn’t die (kinda like a what-if) #ThisIsUs," one tweeted and another wrote, "Dr stole Kyle, he’s not dead. He’s the man with the horse. He looks so much like jack #ThisIsUs." Another viewer posted, "Please don’t tell me Kyle is the man with the horse #ThisIsUs."

Some, however, feel he is Jack Jr. "Is the older man with the horse Jack Jr and the girl his daughter Sadie? #ThisIsUs," and another said, "That man with the horse has to be Jack and that little girl is his daughter! #ThisIsUs."

Another said, "Is this man with the horse, Older Future Jack and his daughter? or this a reach #ThisIsUs." Another tweet read: "Um, who is Sadie? Who is the man with the horse? Is that older Jack? #ThisIsUs."

After these wild theories, can't wait for 'This Is Us' to be back with Season 5, can you?
