I'm cracking up at the thought of the vase becoming a thing. Like Simon rooming with him waiting his turn for the bathroom in the morning and Magnus just walks out with a vase under his arm. People keep going to see him at his loft and the vases are just getting larger and larger. Everyone is confused and trying to work out what is with the vases, are they used for spells? Potions? For High Warlock Stuff??? Really it's just Magnus fucking with everyone.
