When he enters the tournament, and watches Serinth fight three people at once, he exchanges dialogue with someone next to him who says they think it means three times the chance to hit her, but it's a joke, look at these bozos, she's constantly correcting them. He sees that yes, she pauses the timer to correct them of foot work and center of balance. It's like she's training them, and when they finish she says they are getting better. Jagex reaches the conclusion that it must all be scripted, like WWE.
When he calls her name she turns back with this crazy smile and says "There you are." and suddenly it feels like the rest of the coliseum is gone, she's staring at him doing her esper things and he has to shake it off.
