Final Fantasy IX/Summit Station

After a disc change, the scene switches back to South Gate, where the guards are still bickering about the suspicious look of Steiner and the relative merits of various varieties of pickle. Following that, we rejoin Steiner and Dagger, still on the train up the Aerbs Mountains, trying to get to Alexandria.

Rest Stop
After disembarking, go through either entrance to the northeast to reach the Summit Station Rest Stop. At the bottom of the screen, a shopkeeper sells some valuable weapons and armor, in addition to the usual items. Pick up anything you do not yet have and stock up on supplies. If you have a little extra Gil, pick up some extras for future syntheses, and see the sidebar for a way to invest your Gil in a scheme with guaranteed return. Don't forget to equip upgraded weapons, armor, and accessories, both new an old, and reshuffle Abilities for battle.

In the lower-right corner of the room, Nazna the Moogle stands next to Steiner, offering the ability to save and tent. You have a letter from Grimo to Nazna, so select the Mognet option to get a Kupo Nut, assuming you delivered your last Nut in Disc One. After reading the letter, pick the Mognet option again to be asked to deliver a letter to Mochos.

Talk to the gentleman behind the counter to the left to trigger the departure of the train to Lindblum—and to hear someone miss it! Before you follow the voice, open the chest below the desk for a Phoenix Down, then exit through the door nearby.

On the platform, Dagger will see a few familiar faces head into the Rest Stop. Follow them.

Back in the rest stop, Steiner is picking a fight with Marcus and Cinna, members of Tantalus. Break up the fight by talking to both sides individually. The train to Alexandria will arrive, so follow everyone onto the platform and onto the train.

Train to Alexandria
Watch the scene on the train until you regain control. At this point, talking to Marcus triggers an event that stops the train and leads to a boss fight against yet another blast from your past:

Alexandria Station
Disembarking the train on the Alexandria side, you will notice that Part-time worker Mary has finally opened that shop she's been talking about, though it's just your basic set of supplies for sale.

Heading north, you will quickly run into a fork in the road. Your story destination is Treno to the right, but if you are trying to make some extra Gil off the Cotton Robe trick—or if you just really want an Elixir—first go left to return to Dali.

Dali
This is an optional detour, but a necessary one if you are trying to perform the Cotton Robe trick. Go left at the fork and talk to the gate attendant twice to let you proceed onto the world map. Travel northwest to reach the village. Once there, the first building on your right is the inn, where you can save and rest (for 100—talk to the kid in the room with the beds). The first building on the left is Eve's weapons, where you want to buy the same number of Wrists as you did Steepled Hats at South Gate. Her inventory is exactly the same as last time you visited. After that, follow the path to the northeast for your one and only chance at the treasure chest the old woman normally works around. Take the Elixir inside and head back to South Gate.
