Update: Closure on Jessie and Emily

SPOILERS AHEAD.
 In Toy Story 5, we've lost one fan theory and gained another. 
As you might remember, Jessie, the cowgirl doll, and apparently Woody's sister, has had a crippling fear of enclosed spaces and being abandoned ever since Emily, the little girl she originally belonged to, left her in a cardboard box to be donated to charity when she outgrew playing with dolls. While anyone who’s seen Toy Story 2 probably remembers how traumatized Jessie was about being abandoned by her best friend after spending years forgotten under the bed, but this movie offered some much-needed closure for us as well as Jessie. 
After Bonnie, the little girl Andy donated his old toys to when he went off to college, lost Jessie and her horse, Bullseye, they ended up at Emily’s childhood home since the people who found her had read the address Emily had written on Jessie in case she’d been misplaced.

 It turns out that while Emily did give Jessie away, she never entirely forgotten the memories and how much she’d meant to her. The toys discovered a carving featuring Jessie’s name in the tree where she and Emily spent their summers playing together and found a time capsule.

No, it wasn’t full of Emily’s childhood trinkets, they found something much better. A birthday card containing a picture of an adult Emily playing with her own daughter on the tire swing, which revealed that Emily hadn’t forgotten about Jessie, she’d even named her own daughter after her, and affectionately dubbed her as her "little cowgirl" in tribute of her favorite toy. 

We've also gained the evidence that Emily's choice to give Jessie away was made in the cowgirl's best interests. Emily thought her childhood friend deserved a chance to make another kid as happy as she'd made her. Which she did. She became one of Andy and later, Bonnie's favorites! 

They say "If you love something, set it free. And if it really loves you, it will find a way to come back." Which Jessie also did.

See? Other people like this idea too!

The theory we lost was the popular one that Emily grew up to be Andy’s mother. But now that we’ve seen that they look nothing alike, it’s been disproven. 
But doesn’t Emily’s daughter look a lot like Andy’s mom? That would mean that Andy is Emily’s grandson. The timeframe fits, and this means Jessie's story, like Woody and Buzz's, has come full circle.

Besides. we’ve never actually heard Andy’s mother addressed by name. Even though the film crew said her name is Jennifer, that could be her middle name. Jennifer was a ridiculously popular name in the 1970s and 1980s and a lot of girls had to get creative with shortenings and nicknames. My mom, whose name is also Jennifer, told me that.
