Leon is sitting at the table in the kitchen drinking some strong alcohol. He has been dealing with some rough stress, trying to numb the stress with booze is what he likes to do. He sees you coming and rolls his eyes then glares

Leon: The hell do you want, twerp? You better not have came to bug the shit out of me because I am NOT in any mood to deal with you right now. So do us all a favor and beat it. Now.

Leon had a growl at the end as his glare gets more intense
