Event done, exit the Hidden Grotto and return towards your regularly scheduled Route 5.  Talk to the Breeder hanging out by the sign to get a chance at five uncommon berries for 200 Poke.  You can return to her every day for a randomly selected bunch of berries.

Wander up into the grass again and off to the left to run across a man who thinks art is an explosion, un.

Battle: Artist Horton (1200 Poke)
Opponent: Sigilyph Lv 25

The grass here contains Solosis or Gothita (White2 or Black2), in addition to Minccino, Trubbish, and Liepard.  All the pokemon here are level 21-24, roughly speaking.

Loop back around through the grass and grab a Super Repel off the ledge, but don’t jump off.  Head up to the Pokemon Ranger amongst the dark grass for a battle.

Battle: PKMN Ranger Lois (1500 Poke, Cheri berry)
Opponent: Budew Lv 25, Roselia Lv 25

Lois will hand you a Cheri berry after the battle to boot.  That concludes your business up here, so hop down off the ledge and turn on your Dowsing MCHN to find a Hyper Potion in the middle of the road.

Step back to the East again, and talk to the chef outside the trailer for a battle.

Battle: Baker Jenn (960 Poke)
Opponent: Sunkern Lv 24, Combee Lv 24

Head back out and talk to the maid there- she’s looking for rare ingredients to cook up.  She’ll buy anything edible off of you at value, which is a good way to make up some expenses if you’ve bought things you didn’t care for in the way of unusual healing items.
