⋆. 𐙚 ˚𝓣eaching Grim a secret handshake because it symbolizes a deep bond from where you're from and the first years finding out, forcing you to teach them your secret handshake to them too.
I like to headcanon that secret handshakes don't exist in twisted wonderland. Greetings in twisted would most likely be a handshake or a dap up at best, but a secret handshake? Nope, never heard of it.
So you would introduce them to it. Mainly Grim after you taught him a secret handshake.
The thought just came up to you on a random morning while getting ready to go on about your day, until your head was like "how about you teach Grim a secret handshake like how you and your best friend used to do" and so you did. You made up a secret handshake on the spot, taught it to Grim, who surprisingly memorizes it fast and now you two do it all the time to greet eachother if one of you are separated, or if you two finish a particularly hard task and succeed.
The first to notice the secret handshake is Ace and Deuce of course; they would notice how your hands seem to do a secret greeting that only Grim knows how to do when you two reunite after being seperated. Ace would get pissy about being left out, and Deuce would stare with jealousy in his eyes as you two do that thing again with your hands. You finally taught them the secret handshake and now they wouldn't stop doing it with eachother or with you and Grim. Finally perfecting a potion in Crewel's class? Secret handshake, passing in Trein's test? Secret handshake, Managing to finish five laps on the track as to Vargas's instructions? Secret handshake as a celebration. You swear they're trying to numb your hands atp.
Another victim to this is Jack. Jack probably got curious to the incessant handshakes that was unfamiliar to him. He doesn't remember people in the twisted wonderland do that, he doesn't remember a handshake that has five steps before ending. Then after multiple instances of doing the handshake in front of him you made him join in on the fun by just doing the handshake with him, no practice, no step by step tutorial, no introduction, you just went up to him after doing the secret handshake to Grim and did it to him too. You are very lucky that he caught on quick and was very quick to learn after seeing it multiple times. I headcanon that he doesn't do it as much but he does still do it, just not as excessive as Ace and Deuce. It's just a way to insure you're friends y'know? Like a confirmation of sorts.
Epel would definitely notice the secret handshake and will definitely demand to do it too. You would have to teach him three times until he could grasp it, but once he does he has an undying grip on it and will do it to y'all to make himself feel 'manly' because does anyone have a secret handshake? Does everyone have a sick greeting as this? No, so that's why he does it to greet you guys, he does it to show off, and he does it to feel smug. He just loves how secretive he is. But he will get used to it so much that he accidentally does it to other people, his ands move too fast for him to comprehend that he did it to Rook and not you guys. You can imagine the horror he felt after realizing it.
Ortho observes the secret handshake with interest and curiosity but will not ingage or ask questions, he thinks that it's personal so he doesn't really ask about it nor ingage unless told to. This will go on until he could practically memorize the handshake. You guys will have to ask him to join or better yet do it to him. He'll be very happy and enthusiastic after being part of it and will show it off to his brother. Be warned though, if he finds out that you could essentially make different kinds of combinations of handshakes he will make difficult and different kinds of handshakes and show it off to you guys. You probably have three more handshakes because of him.
Sebek is last because he's stubborn and doesn't understand human culture all that much. Although after allot of encouragement and persuading for him to join in on the fun but rest assured, after you do he'll very much feel very included and will show it off enthusiastically to Lilia and Malleus, but he will never say that to your face. You will have to engage first though if you want to do the secret handshake with him the first few days because he's quite stubborn. But after a few weeks he'll get more comfortable and will eventually do it in front of others or to greet you guys, however he'll treat it as if it's a secret promise between knights. A little warning though he does get smug and will gloat about it to others in earshot, the whole school will know about it in a few weeks if you don't shut him up about it.
Every single one of them gets very protective of the secret handshake and gatekeeps it hard to other students. If the students make fun of it? They'll get very furious and defend it as if they're life is on the line, if other students try to copy it? They'll make it known to the world that they did it first and they are the superior to secret handshakes and will not shut up about it.
They'll do the secret handshake to you one last time if you go back home, it's shaky, their grip is too tight, and their hands often miss yours. But its theirs and they are proud of it. After you go back, all of them will avoid using it to greet eachother because it reminds them too much of you, but they do it in front of the mirror to not forget about it. Rest assured though, after a few months they'll do it again to eachother, but this time it's much more sentimental, and too heavy to be considered normal.
𝗔/𝗻: had to sneak in a little bit of angst in the end because twst is full of angst— THIS WAS SUCH A HASSLE TO WRITE I'M JUST GLAD IT'S GONE IN MY DRAFTS NOW OMG 😭 I'm finally back to my usual writing schedule ‼️ I just hope I continue this while I'm in vacay
