KFP4 Theory: Is Zhen Secretly Related to Tai Lung?? (Hear Me Out!)

Okay, so I finally got around to watching Kung Fu Panda 4. I'm a newbie to this franchise, I know, but I'm trying to catch up on classics! And honestly, it was... alright? Not blown away, but I had a good time. Anyway, I've been thinking about Zhen, the fox character Po is training. Something feels off about her back story. It's like, too vague, you know? My theory is that she HAS to be connected to Tai Lung somehow. Think about it! She's obviously incredibly skilled, but also clearly has some emotional baggage and a chip on her shoulder. She also has that ruthlessness about her, that kind of cold pragmatism that Tai Lung showed. Maybe she's like, a descendent? Or maybe she was trained by someone who admired Tai Lung's fighting style? I just don't buy that she's just some random orphaned street urchin. I think there's more to this. Also, I REALLY think they're setting her up for either a redemption arc or a villain arc. She's just too interesting to be a one-off character. I was specifically paying attention to that scene when Po talks about the need to trust the people you train - I think Zhen is going to let him down in some MAJOR way. Maybe even accidentally unleashing a bigger evil on the valley. What do y'all think? Am I reaching here? Or is there something more going on with Zhen that we'll see in future movies? Let me know your theories!
