Not all of these are confirmed, but i think i saw...

A woman wearing carlys jacket ( could just be lazyness on TTs part )

What could be the St John dairy

Vernons gang but no Vernon

Beatrice from episode 3 ( the woman you either shoot or use as distraction )

The Gas station ( kenny says somebody grabbed duck at a gas station )

What looks like carly/doug dead by the roadside ( pause trailer at 34 seconds and look to the left of the road ) 

anyone see anymore?
