D.Gray-Man: Is the plot still the same after all that has happend?

Hey I just started re-reading D.Gray-Man and I have a question? Does the plot still stay the same after all the things that happends in the story? Like for example these are plots that I know of.

Beginning (Moa Ark, Joining the black order,Ghost of Matel and Rewinding Town)
Plot: Go find more innocence so we can get more excorsistes to defeat the earl!

Noah Appears The 1000 year prelude is over (Arystar Krory Ark, The Fallen one, On the ship to Edo)
Plot: The Earl is finally taking action even his family is involved! Plus there after the heart! One of the generals have been killed meaning there pretty tough plus they think one of the Generals is the heart! Go protect the Generals so the Earl can't destroy them and possibly obtain the heart! Because if he does its the end!

Edo (The collapsing ark and so on)
Plot: What the Earl is in Edo! Plus he has a manufacturing plant! He is planning on downloading data and moving to a bigger plant to make more Akuma! We got to stop him! P.S: I don't know if this is correct.

So really I'm saying do I have everything right so far. At the beginning I only read up to ch 102 when Allen is fighting Jasdebi. Now I am at Vol.7. which is right after the fallen one ark. so I'm just asking after the tragedy that happend on there way to Edo (Suman like destroying a ton of stuff) and when they make it to Edo is the plot still "Trying to find General Cross so we can protect him?"Sorry I'm a big fan and I just wan' t to make sure If I have every thing right. XD
