Well, first things first -- it looks like you need to reconvince her after last time.

Ah, there she is, just across the Arena tent! She's actually already looking over at you, so you give her a big smile and an overhead wave as you walk towards her to begin your training session. It looks a bit like she's glaring at you, but that wouldn't make much sense. Maybe she hasn't actually seen you yet, and she's just looking at something else in your direction. That would make the most sense, since now that you're walking towards her, she's also turned around and started going the other way. You pick up the pace a bit to catch up with her.

"Gold Rush!" You call out, lightly jogging to keep pace with her. She shoots you a scowl over her shoulder, then starts jogging as well, running out of the Arena tent with you in pursuit. A-ah, so she did see you, then...

You duck under the flap of the tent and rush out after her onto the Courtyard grass.

"Gold Rush!" You call out again.

“You knocked me out!” She shouts back at you over your shoulder as you chase her around the Courtyard.

"Gold Rush, please!"

She stops in place, turns to face you, and crosses her arms, scowling angrily at you. You slow to a walk to close the distance a bit more, then stand still as well.

"You knocked me out!" She says accusingly. "I trusted you, I brought you into my dorm, and you knocked me out! And then you left!"

"I tucked you in after, at least!" You point out, defensively. Gold Rush's face goes bright red, and her arm comes up to point away from you both.

"Leave!" She shouts.

"Gold Rush-!"

"LEAVE!"

No, this is all wrong! You can’t let her get rid of you -- you still have to train her! Does she really not want you to coach her just because of last time? There’s only one thing for you to do....
