What if the "24 minutes" is actually an OVA?

They didn't include the 139.5 chapter in the episodic format. What it could be implying?

Imagine it opening with the CUT 004 (theory) and it will show up how Mikasa kills Eren and how he dreams about Paradise being bombarded and then he will woke up, from lying down on the ground (instead of leaning on the tree)? And further it could continue with Beren and at the end, they could hint us towards MOE 🤔
