Great chapter. The appearance of Lance. I thought this part was pretty good:

Weezing’s crest shimmered a glowing orange. Maybe a fire attack?

“WEEZING!!!!!!” The Pokemon roared, her eyes blazing with orange flames. The heat suddenly rose in the Gym; it was now stuffy and sweltering. Weezing still forced the energy forward; creating the sunny day, but shortly afterwards sent a beam of white light in Beautifly’s eyes.

“Flash?” Janine asked herself. “And sunny day...together?”
A Sunny Flash? Poor Chris, Krystal's leaving. One thing I've noticed: Neither of them have mentioned "The Kiss" in Viridian Forest. Maybe it'll come back up before Krys leaves?
