"Later" in this game always means after you've done other things, not after some real time has gone by.

So you did the "collect the boxes" quest on Route 4? And AFTERWARDS you met Mewtwo on Route 7 (north of Violet City)?

I'd recommend you continue your journey to Nightshade, maybe do a sidetrip to the Isle on Route 11, and return back after you got HM02 Fly. I want to warn you however that it MAY be that there's a bug that will make you unable to continue the quest line.
