News has leaked out that next week's Hawkeye episode 5 (the final episode of the series) is going to be the big surprise we have been waiting for. After Hawkeye episode 4, we are beginning to get an idea of what to expect.

The news comes from the latest edition of TVLine's Matt Webb Mitovich's Mailbag column. Reader Greg asked, "What's up with Hawkeye?" When asked, Mitovich played along this week, saying, "I hear that only in Episode 5, they're going to blow up Twitter a little bit." Of course, spoiler alert below.

And what does that mean? Well, nothing that Marvel and Disney Plus haven't already teased in the current trailer. There, young Maya Lopez/Echo is pinched on the cheek by her "uncle," and a masked figure wearing night vision goggles asks Kate, "Who is that?"

Maya Lopez/Echo is seen having her ask, "Who is that?

Speaking of Maya's "uncle," the big reveal in "Hawkeye" episode 5 is most likely related to the Hawkeye fan's big theory that people kept shouting at the screen in "Hawkeye" episode 3. That theory is that Kingpin Wilson Fisk is coming to Hawkeye and will finally appear in the MCU. And that Vincent D'Onofrio will play him.

This theory is perfectly in line with the news that Charlie Cox will reprise his role as Daredevil in the MCU. Because without his most iconic rival, why bring back the Kingpin?

In an interview with Screen Rant, Marvel Studios head Kevin Feige practically agreed, saying, "Whenever a character returns to the Marvel sandbox, I always say it will be another tool in the MCU's storytelling abilities. As I've said before, the good news is that everything will be clear when people finally see it."

And this makes us wonder if Daredevil will actually appear in "Spider-Man: No Way Home," if Jessica Jones will appear in "She-Hulk" (the two are friends), and if Luke Cage will be flitting about in another upcoming Marvel movie or series makes us wonder if they will make an appearance. Whether their Netflix-based adventure will be canonical remains to be seen (though their show does mention the Chitauri assault on Manhattan and other big-name MCU heroes). However, I am not wondering about "Iron Fist".

But we have days until Episode 5, so let's talk about what we'll see this week. Then there's the long-awaited reunion in the "Sex and the City" revival of "Just Like That," followed by the Paddy's Pub mess in "It's Always Sunny in Philadelphia" season 15 episodes 3 and 4.
