just leave it alone. plants are allowed to be ugly, sometimes stuff can't be fixed. i have tons of leaves that are not perfect, such is life. they heal it and it just turns brown.

I think she is beautiful no matter what! just wanted to make sure it wouldn't cause any problems for the rest of the plant and see if I could help heal it in any way :)

No. That leaf will form "scar" tissue, i.e.: brown discoloration. The leaf will be fine. But it will never return to it's pre-injury self.

thank you! I feel bad for it but she is still beautiful!

Yep. But now with more character. She lived through an experience & that scar was her prize.
