Spoiler warning! This article contains plot details about events that occur later in the game.
Shelly is first encountered in the Lower Peridot Ward, where she helps a girl with her lonely Kricketot. If the player accepts the Kricketot, Shelly will thank the player before leaving.
Later on, after the death of Corey, Shelly is encountered again outside her Gym, witnessing the disturbing image of Corey's body. Victoria claims that Shelly is not in a good state to do Gym battles and suggests the player to check out other things before doing the Gym battle.
After the Gym battle with Shelly, the player teams up with Cain and her to help Charlotte, Anna, Noel, and Heather escape the City Orphanage. All of them escaped to the underground railnet before being kidnapped by Team Meteor.

A special report from... the Investigation Squad!
Yo, Reborn City! What's up?! We're here with the Reborn Showdown giving you a look at the Leaders of the Reborn League! I'm your host, DJ Arclight, now on air!
Let's talk about Shelly, Leader of the Lapis Ward! She's a timid soul with a passion for reading and knowledge. In fact, it's rare to see the girl without her nose in a book, but it's paid off in spades. All that studying means that she knows just what kind of tune to have her Bug types play in any battle!
Shelly herself prefers double battles, using rain to cover her weaknesses and overwhelm her opponent. Her signature Pokemon, Illumise and Volbeat, are the prelude and finale each to her tactical advantages, so if you find yourself facing the bookworm, focus down her supports right away!
That's all for now, but remember, Trainers, Keep fighting with everything you've got! Hold your spirits high, and even you can defeat the Reborn League!
