Truth be told, Jon and Karen were pretty evenly matched. Victory was often decided by who best took advantage of the other's mistakes. After four close matches they were tied 2-2, demonstrating just how balanced their pairing was. Karen decided it was time to tip the scales.
"Restroom break," she when they returned to the character selection screen. "Feel free to stay warmed up with a CPU match while I'm gone."
"I'm kinda thirsty, myself," Jon replied. "Want to stay for dinner? I'll ask my mom while I'm downstairs." Being long-time friends and well-behaved in general, they were in good standing with each other's parents. Jon's mother Linda would often invite her to stay unprompted.
"Sure!" Karen beamed, then fished her phone out of her back pocket. "I'll text home real quick."
Jon nodded and headed off toward the stairs.
Once Karen sent her message, she grabbed the red sweater and headed for the bathroom. She really did need to use the facilities, but now was a golden opportunity.
