Can boredom make people angry? In Fernanda's case, yes it fuckin can! For starters, she wasn't a paragon of patience, and it had been since forever (for her perspective) that she had gotten any kind of match in the League. She had built up a good amount of frustration, and the only way she wanted to get rid of it was by punching a bag until it exploded, or her knuckles broke. Whatever happened first!
The luchadora punched that poor bag with more wrath and passion than a person could handle. It would be quite intimidating to hear the chains that kept it in place sounding like they were begging for her to stop, and the view of that muscular (although still, very pretty) woman striking her fists repeatedly against that sack that trembled horribly with each hit, probably wanting to fly to the horizon if it wasn't for the aforementioned chain.
"HNNGHH! Motherffffuuu!!! Grah!!!" She was clearly in a sour mood, it looked like those emerald eyes just stared at the hole that her fists wanted to dig inside that old bag. The rest of the world might not even exist for all she cared at the moment. Poor unfortunate soul the next person that made themselves the next target of her violent onslaught!
