Ingrained habits If Mags is not paying attention he fidgets or hums! I suppose you could consider the way he absolutely babies his harp and oils it daily, checks the strings etc as a habit too XD
fears/phobias Mags does not actually like heights much XD HE HAS SEEN TOO MANY PEOPLE TAKE JUMPS OFF THINGS OKAY. Also he has deep rooted fears that by throwing away the silm he has essentially
He also has abandonment issues and I don't even think you can call it fear so much as is utterly convinced that everyone he loves leaves him eventually
what gets him flustered forgiveness. He wants it, but he is convinced he does not deserve it and can never have it. Also, just... people being nice to him, sometimes
And, lol, this is a running joke, but there is a fanfic which references a song called the Elf and the Fruit Vendor, and Mags will either sing the whole ribald thing for you or get REALLY EMBARRASSED about it
The song does not exist! It's basically the fanfic writers version of the Noodle Incident lol, but we do know that at one point it involves Turnips, that verse 31 is the most explicit verse, and that it
He asked the fruit-seller and she did reply,
for a turnip hath many a purpose
besides the spicing of pie...’"
I was just reading about him today
