I finished doing the quest for the Glalie Mega Stone but when I spoke to the last NPC he didn't give me the stone. I've done the quest several times and nothing.

Good Day @Gabriel10hdz

 

According to our database you have acquired 3 out of the 4 fragments required for this quest. The fragments come from the following locations:

• Seafoam B4F: Requires a Pokemon with Flash
• Ice Path B1F: Interaction with the stone  then wait ~25 real-life seconds before interacting with it again 
• Lake Acuity: Surf counterclockwise through the edge of the lake
• Shoal Cave: Requires a Glalie with 70 or less total IVs in the 6th party slot.

Once you have all four fragments then you should talk to Scientist Paul in Pewter City's Musuem. Afterwards he will require you to show him a full team of Ice type Pokemon (fusing the fragments together for Galitite upon completion).

 

I hope this information assisted and I look forward to your response.
