I was just watching the newest episode, and I do follow the manga, up to the newest chapter, but there are some things that were said in Ymir and Reiner's conversation that for some reason I don't know the answer to, maybe I forgot about it, or maybe they weren't answered yet in the manga- but hopefully someone would be able to answer them for me.

When Ymir asked reiner how come the titans that arose from inside the walls could move at night, Reiner told her she should already know the answer- how come she should know the answer?

Ymir speculated that Reiner and Berthold are trying to reach the Beast titan because he is their way back home, that is another thing I don't understand, how was zeke their ticket back home and why couldn't they just go back home on their own? well now that I think about it since they are living on an island they need ships to go back home, and since they saw zeke on the island they must have figured out there is a ship waiting on shore, but is there something I'm missing?
