What do you mean by funny movements?
For me personally, I usually don't "treat" a cut like that. IF no one is bothering the wound, then I leave it alone. A lot depends on what it looks like in person, I might dab on a bit of Blu Kote.
You may want to dab a bit of Blu Kote on it. It's her earlobe looks like to me. Barring infection it should heal fine. Some of the tissue may die and eventually fall off depending on the damage.
