Been thinking a lot about Harry Potter recently and I'm 99% sure Hagrid and Charlie were close friends.
Who loves Dragons?
Hagrid and Charlie.
Who chose to dedicate their life to a dangerous magical creature, despite having the chance to do other things in life?
Hagrid and Charlie.
Who helped take care of the dragons during GoF?
Hagrid and Charlie.
Plus Hagrid tried to keep a pet dragon, which canonically Charlie then helped raise in Romania.
They. Were. Dragon. Dads.
Plus they're both like the sweetest characters ever. If they weren't friends, I'm suing.
