Mercedes could call Hubert something like "Boo-bert", something ghost related like that as a pet name
As adorable as this nickname is....I can't help but feel like this is related to another blog entirely...
On the chance this isn't related though, it is an adorable nickname! Just imagine Mercie even making a little motion whenever she says the "Boo!" In the nickname...Hubert would be trying to fight down the amount of warmth flooding his being at that (even if his face is clearly tinged pink).
