How do you get to the real Janine in gym from SoulSilver?

You can't actually "get to" the real Janine in Gym in SoulSilver.

Here's why:

* Janine's Gym is a battle simulation. The Janine you fight in the gym is a computerized version, not the real Janine.

* The real Janine is elsewhere. After you defeat the simulation, the real Janine will appear outside the gym, and you can talk to her.

So, while you can't access a "real" Janine in the gym, you can encounter her in the game after defeating the simulation.
