Since his brain moves at a mile a minute, during my improv, I feel like the most Jacque thing to do is to ignore the problem entirely. The " sharp horn" horns bit is just headcanon. As if Jacque's dad had lied to him as he grew up. His father is a deer but claims to his son that he also has horns instead of calling them antlers, because he is ashamed of how they compare to his son's as he's aged. He knew they would grow to be strong one day, so he's lied to him his whole life to make himself look equal. Jacque being oblivious never saw a difference. A testament to the strange and sometimes one-sided pettiness in their relationship.
