Pokémon Lab (Part 3): The big departure

On arrival, Xander gives you 3 more memos (3, 4 & 5). They could always come in handy, especially since they once again concern Shadow Pokémon and purification. Got them!

Lily, Michael's mother

Go and give the part to your mom, Lily, who is still upstairs with a professor. (By the way, one wonders why she is always there!)

Answer her question about the Heart Gauge of your Teddiursa (yes or no, it does not matter), and she will advise you to go to Agate Village to visit a friend of hers, who will guide you in purifying your Teddiursa.

Teddiursa.

Off you go again, but without your sister this time (good riddance).

Head for Agate Village!
