We should already know that trailers can be misleading. Some of the segments shown in TWD and TWAU trailers never showed up. This is probably due to people hacking into the files and leaking the story causing them to rewrite the story. The hype is real before these episodes come out. Trailers are only meant to tease you. You should also never become hyped up before your favorite movies or shows come out.
In the Walking Dead tv series season 4 trailer it showed Michonne looking at a map to Macon and riding a horse. This never happens in the whole season.
So basically I'm saying never get over hyped because sometimes things will never happen at all. Rebecca was also supposed to have her baby in 203 but never happened either.
