Summary
What if the Westallen wedding hadn't been interrupted by Nazis?
"You need me to do what now?" Sara had to bite her lip to keep from laughing given the look on his face, which also made it clear this was the first time Ollie heard this and it had not been part of the deal when he'd accepted to be one of Barry's best men.
"I need you to help me out here. You're my best man. Look, the wedding planner was supposed to provide us with personnel to do that, but for some reason they didn't show up… so I need you to do it." Barry looked a little flustered and sheepish, she had to give him that but still asking Ollie to make a fool out of himself in front of all the guests was a big request. Especially after last night.

Summary
So, unlike my Duet Supercorp Edition (check it out), this won't be as easy as swapping Mon-el with Lena, (Which is a better match anyways). So I am doing a bit more with this one. So, instead of swapping anyone, I'm adding in an OC. An OC who has been third wheeling Supercorp, (I mean who hasn't) for quite a while. This is NOT a OC x Supergirl/Arrowverse character fanfiction. Just an OC third wheeling.
So, just a quick recap on my OC. His name is Robert "Bob" Star. He is head of security at L-Corp. He is also a superhero. He calls himself Shockcharge. Robert actually joined Kara when Barry came by and asked for their help with the Dominators, which is why he got an invite too.
Lena knows, was never angry. And so, with the reveal of Mon-el's wife, Kara went into her depressed state. Then, as you know, Kara takes her sister, to help with her breakup too. And being the matchmaker he is trying to be, Robert takes Lena, as a friend.
I don't own any of the characters except Robert. Most of the story line is the CW's except for the extra stuff I added in. I am also aware the timeline on this may be a bit mixed up. Just roll with it.
