Is anyone in this fandom old enough to remember when ships as well as platonic friendships had little like ... for lacking a better term ... "titles?"
You know like how "do you permit it?" is Enjolras x Grantaire's ship title/phrase in the Les Miz fandom?
Popular OCxCanon ships sometimes even had their own little titles as well depending on the fandom.
We should bring that back.
I propose "a perfect fit" as Miranda x Roland's ship title/phrase.
(I have one other one I like, but it's tied more to something I have on their ship playlist. This makes actual sense for them from canon.)
Either "we'll do it together" or "great and grand" for Cedric x Greylock. (Personally, I like the first one better because I like the quote form "Baileywhoops," and it's cute.)
As far as the platonic friendships go, I was thinking:
"being friends & being brothers" - Cedric & Roland's platonic friendship
(Though, I am open to suggestions on any or all of these, but especially Cedric & Roland's tag. I just like this iteration because it's a nice summary of their friendship from canon in a handful of words that's VERY loosely based on a quote I associate with them.)
Additionally, for people who like them as a ship you could (probably should even for organizational purposes) have a different little phrase for them as ship instead of a friendship. Personally, I could see either of these characters as bi ... just not for each other?
"i believe in you" or "they were once incredibly close" - Cedric & Cordelia
Now, I am partial to "his little arthur of sorts" for Sofia & Cedric's friendship. (But, that is because I used it in one of my fics, and I love the idea of encapsulating their Merlin & Arthur parallels somehow.)
But, in reality, something like "a far, far better me" - to cite the song, in S3- or "to be friends is the most powerful spell" - again because it's a decent summary of their arc - would be good options for Sofia & Cedric's platonic mentorship and friendship phrase tag.
(The second option may, or may not, ... okay, it is ... lowkey based on a quote by Van Gogh ... but COME ON! It works too well doesn't it!?)
These are the only ones I could think of off the top of my head, but I like them?
