"If you don't let her out, I'll, uh..." You thought, before you get an idea, albeit a not-very-good one. "I'll have to fight you!" Gary stares at you deadpan before bursting into raucous laughter, making his belly bounce with every laugh.
"Really? You think you can beat me in a fight?" Gary taunted him, clearly not believing what he was hearing. The more you thought about it, though, the more confident you became. Not only were you positive that you were smarter and quicker thinking than the lug head, there was a definite chance that he would be weighed down by his sister in his gut, plus there was a high probability that he wouldn't take that into account.
"As a matter of fact, I do," You respond, getting into your best fighting stance. Gary is taken aback, surprised at your determination, then snickers to himself at your foolishness and puts up his dukes.
As the saying goes, the first move decides the rest of the match. Gary was the first to move, lunging forward to throw a haymaker. His movements were more sluggish than usual, as you predicted, and you dodged it just in time. The power of the punch worried you though. Even though he was slowed down, that wouldn't take away from his strength much, meaning that even one hit could mean a loss for you. The thought made your stomach tremble, but you managed to stay focused.
You swiftly punch him in his side, before dodging away to prepare. The punch didn't do much, plus you could feel your fist was slightly weaker and more rubbery, needing only a second to reform completely. Not only was having to reform after every attack a major disadvantage, but you only just realized that you wouldn't be able to make any gutshots, considering going for it would hurt Mary.
Considering all these factors, the way the fight goes...
