However, mainly is a repeating what was said in Avenger Issue 3. Also the whole issue ends withe the White Event starting so.
It is very clear in this White Event Captain Universe has a large part to play. The only real new information from NightMask was said on page 19, which further implied how this is all about Captain Universe.
Issue 6 also covered(not enough but some of it) of Captain Universe showing that the host is basically broken. Which might make Captain Universe powers be stronger as there is no host hindering its powers or it is actually weaker because no host can focus it's powers.
This one is pretty interesting because its in the resume of what happened in Issue 3 of Avengers. But this actually did not happen. NightMask did not say this while carried by Ex Nihilio.
It is However what he said in some of the pages in issue 3. About the White Event
It is kinda like Spidey says here, even knowing what NightMask actually says it is pretty much gibberish between. That its coming and that the system is Broken.
However, we also learn in this issue that Captain Universe is broken as is the host it is inhabiting. So something has broken the whole Universe it seems.
Repeating the old good varning.
Then NightMask comes to an important comment. And what I was talking about eariler.
This is the page Captain Universe also shows she(IT?) can of course also talk Builder Machine Code.
And NightMask calls her Mother.
So here it clearly shows she is deeply connected to the whole Mars thing and the white Event.
Then it turns into another try of NightMask to tell his name to Tony.
After this NightMask repeats his warnings and it is translated by Captain Universe to the others.
This is pretty much what the next pages say as well but not exactly the same.
In the end page of the issue its a small note in Builder Machine Code.
Hopefully now Avengers 7 will explain a lot of what all this means.
However, I do predict that the whole Ex Nilihio start won't just stop at the white event. As in Avengers 4 with both A.I.M gaining bio mass from him and Hyperion raising a new race in secret. These 2 factors probably wont be in the White Event and will instead bite the Avengers in the ass at a later stage of this run of Avengers ( run 5).
