TAZ headcanons for @twinsweek about when the ipre crew first meets/goes on their mission:

Magnus can tell them apart from the beginning, just off of gut instinct. He never gets them confused, ever. Lup is working in the kitchen, wearing what is clearly Taako’s clothes. Magnus walks in, and before she can even try to trick him “Morning Lup” “How do you DO that!” The other crew members ask for tips on how to tell them apart but he’s so unhelpful. “One’s just… Taako? And then there’s Lup?” The twins are pleasantly begrudgingly surprised while the rest of the crew is jealous and frustrated that he can tell so easily.

Lucretia’s entire job is observing and recording data about the crew and their mission. She pays very close attention to everyone on the crew, so she learns to tell the difference between the twins very quickly: their different mannerisms, vocal ticks, etc. Knowing that the twins will sometimes try to trick everyone by switching clothes and pretending to be each other (they’ve been doing this since they were kids, they have a lot of practice) Lucretia will usually do a quick once over and take everything in about who she’s talking to before she responds, especially when they’re all still getting to know each other.

Barry has a bit trouble telling them apart at first. Mostly because the twins are very overwhelming, especially when they’re together, and he is a pretty reserved guy. Barry spends less time trying to tell which one is which and more time just trying to survive his interactions with them. Once he gets to know them though, he can easily tell them apart. The twins are very different people, and once Barry gets to know those people it’s not hard to tell who’s who. (And of course that’s when he starts to fall in love with Lup and the decades of pining begin…)

Merle probably takes the longest to tell them apart. Mostly because he’s easy to trick, and they enjoy tricking him. Then again, one time Lucretia swore she saw Merle wink at her in the middle of one of the twins pranks. Later he responds to her inquiries: “Eh, it gives them something to do,” and Lucretia suddenly isn’t sure just how much Merle actually can’t tell them apart and how much he’s indulging them to lighten the mood.

Davenport gets the twins mixed up just as much as he gets everyone on the crew mixed up: literally all the time. Like a parent that calls the names of all of your siblings before they finally get to the name they were trying to say, Davenport says the wrong names all the time. Magnus and Merle, Lup and Lucretia, Taako and Lup… One time he called Taako Barry and Taako wouldn’t let him forget it for the rest of the cycle (and wouldn’t let Barry forget it by stealing his jeans and his glasses to master his “Barold Impressions”) He knows his crew like the back of his hand, but sometimes finding the right name for which person you’re talking to is just too difficult.
