Barry and Iris' Arrowverse wedding may have been sabotaged from within

The wedding moment comic book fans have been waiting for finally arrives tonight, but not without a few hiccups or uninvited guests. This year, the crossover event between "Arrow" , "The Flash ", "Supergirl" and DC's Legends of Tomorrow is called "Crisis on Earth-X". The superheroes from each show gathered together to celebrate the wedding of Barry and Iris. . Now, if anyone thought this day was going to go smoothly, they were dead wrong. A group of villains from Earth-X— On a parallel Earth where Germany won World War II and Arrow, The Flash and Supergirl were all evil the sweet ceremony was just minutes before the happy couple were ready to say "I do." Broken. But just before things go awry, the show drops a small (and big) clue as to how the villains found Barry and the gang. Who is the mysterious waitress who talks to Barry in The Flash ?

Just as the ceremony was about to begin, something happened. Interestingly, in a room full of superheroes, no one took a second to pay close attention to who entered the church. Well, except for the wedding planner, who jumps to the front of the building and directs each guest to the bride's side or the groom's side. But like everyone else, she let the waiter wander around the room without being disturbed.

While handing out water to guests, a mysterious catering waitress made a beeline for Barry. Their awkward conversation lasted only a few minutes, but she kept offering him water that he didn't seem to want. It sounds innocuous, but the fact that she won't take "no" for an answer means one of two things: one, she's really bad at taking "no" for an answer; Not good at taking "no" for an answer. One or two, there's something in the water. The unnamed woman began gushing that she was "so excited" to attend Barry's wedding and that she felt it was "going to be a wedding that lasts forever." Oh, the irony.

Barry looked completely devastated and confused. Barry didn't like her cheerful smile. When he asks if they've met before, the waitress's quick change of attitude is a huge clue that she's not who she seems. Before she walks away, she says she's nothing more than a complete stranger, but the way she grabs Barry's arm and tells him to make sure he says "I do"? Yes, no. She's definitely onto something, and she's not a nobody.

Still, maybe that last line means she's not a villain but someone trying to help Barry and his friends. (One popular internet theory wonders if she's actually Barry and Iris' daughter from the future.) If so, the mystery woman could indeed be giving Barry a better hint that something's brewing than the meager hints she's given danger.

Still, it was clear this waitress was offering more than just water and hors d'oeuvres. My money is on the theory that she's also from another universe and is working with Nazis from Earth-X. In fact, it's no coincidence that things get a little confusing just minutes into her conversation with Barry. where is she? Nowhere to be found. Then, at the end of the episode, when Dark Flash is yelling that he's very frustrated with the villains and continuing to storm the building despite his orders, Dark Arrow and Supergirl mention that they got the "signal" and start action.

Who else could they get a "signal" from besides Barry's waitress friend? Fans will have to wait until the two-night crossover ends to find out all the juicy details, but something tells me the brains behind the whole operation is hiding somewhere in the back of the kitchen.
