Garrech Mach Academy Year headcanons

I was reading old posts from the Reddit and found one about some things the students did during their Academy years (AKA pre-timeskip). Of course, you're able to post headcanons that are NSFW or spoiler related headcanons.

These are mine:

-After the whole flame emperor identity reveal, the night after that, regardless of route, Dimitri went to the training grounds and beheaded the all the training dummies. When asked about what happened he just said "I need to practice if I have to behead her"

-Lysithea always carries a bag full of sugar with herself if the food they serve in the cafeteria isn't sweet enough for her

-There was a Tea Time club inside of Garrech Mach, the members were Ferdinand, Lorenz, Constance & Raphael. Why was Raphael there? Well, when asked about itz the rest of the members said "he has an exquisite paladar when it comes to tea". Meanwhile, when Raphael was asked about it, he just said "I can't say no to free sandwiches and drinks".

-Likewise, there was also a Horse club, which was made by Marianne, in the beginning only her & Byleth were in the club (the latter one joined out of pity for Marianne) but later on Ingrid and Ferdinand also joined the club

-Bernadetta often goes to the kitchen at night to eat food alone, she sometimes encounters either Byleth or any of the ashen wolves, in the case of encountering them, Bernadetta's immediate reaction is running away as fast as possible

These are my headcanons for now, what are yours'?
