I'm fine with things between seasons 1 and 2 being a little mixed up. At least it looks like the writers are getting a handle on sorting out the mess they caused - they have no choice now because of plot reasons. Also, I'd go with S4E1 being about two years after the Pilot.
And I'm toying with the idea of Garrick showing up shortly after Luna's Return. This not only gives Garrick ample time to settle in and establish himself as the cordial recluse of Ponyville, but it even lets him have a bit of time to warm up to the others somewhat... to the point where he at least starts helping peo^H^H^H^H ponies out of tight spots and advising others. Later after the incident with Discord, Garrick will probably start taking more active roles in the community.
EDIT: Fun idea. When Garrick 'helps out' his brutal methodology can sometimes lead to the ponies questioning themselves, wondering if it would have been better after all if they had not asked for garrick's help. Example: Garrick does not drive off the hydra that went after Twilight. He kills the damn thing deader than a doornail.
