#3. Dominik takes a page from Seth Rollins' book, gouges his eyes
Wouldn't this be a sweet one for Dominik Mysterio? The entire feud between Seth Rollins and Rey Mysterio heading into Extreme Rules was an "eye for an eye". The eye-gouging has been one of the most essential parts of the story told in this entire saga.
Storytelling is what's most important and Dominik seems to have a good grasp of it so far, even though we've seen so little of it. It seems clear that not only is there a massive experience gap between Seth Rollins and Dominik Mysterio, but given that Rollins is truly among the best in the world, it would make little sense for Dominik to win clean.
If there's a No DQ stipulation (which there ideally should be), the best course of action for Dominik to win would be revenge - by gouging Seth Rollins' eye or even both his eyes, blinding him, and giving Dominik Mysterio the victory.
It would be a fantastic piece of storytelling if Dominik did to Rollins what Rollins did to his father, Rey Mysterio.
