But the experts say he saw it on the newspaper! Nevermind that the reverie is literally happening while he's looking at the window. 
I gave the complete analysis along with the timeline of events for that moment in my post here.
Mihawk’s Observation Haki
Ever since the Reverie event was resolved I had this thread planned because this is probably one of the most controversial topics regarding Mihawk’s powers/abilities.
You guys probably have come across theories that say Mihawk was using Observation Haki to find out the what happened at the Reverie in chapter 925, but all those theories get pushback that Mihawk was just reading the newspaper to find about the events.
I am not sure if someone has already proved this before, but I’m still going to try giving concrete evidence that Mihawk actually was using Observation Haki. This is a bit complex theory so I will first draw the timeline of the events.
First let’s establish the reverie timeline:
Reverie Timeline
I know this may seem useless at first but this will play the most crucial part of my theory.
We first hear about Reverie in chapter 801 from King Riku at the end of Dressrosa
At the same time in chapter 823 – All the kingdoms from around the world are getting prepared in leaving for Reverie.
It takes SHs a decent amount of time to reach WCI. We don’t know exact no. of days so let’s just say it takes them a few weeks. After reaching Totto Land they find out about the weeding which is in 3 days. SHs leave WCI the next day of Tea party.
Now in Chapter 903 we see all the Kings gathering at MariJoa which took about a few days. From chapter 903-908 all the events are of the same day before the Reverie discussion began. Here we also find out that reverie is a 7-day event
Chapter 903
Chapter 908
Chapter 910
And now comes most crucial part of my theory which I’ve divided in 3 segments
FIRST PART
At the beginning of 925, Perona finds out Moria is alive. Newspaper says Moria is going on an attack spree with his zombie army, we find out he was looking for Absalom and that later lead him to Hachinosu.
First is that on the Fourth Day of the Reverie Sabo and the revs fight against Fuji and Ryokugyu.
Second is that Big Mom has started chasing Luffy to Wano. Note it doesn’t say that Big Mom has reached Wano, it only says she has started chase.
- Big Mom leaves WCI and is enroute to Wano to kill Luffy which is around the 4th day of Reverie. Meaning this is before act-2 of Wano. This is around the time when Luffy is thrown in Udon prison.
- Kuraigana scene and Hachinosu scene are happening parallelly. Meaning the newspaper Perona read and Blackbeard read were the same. And yet Both of them still didn’t have the slightest clue about Warlord abolishment.
- Reverie still had 3 days left.
Now comes a complicated part again to align the timelines and this may seem useless but trust me this will make sense.
In chapter 951 there was this small panel which at first may not have seemed important, but later we get the info from Chapter 956 which gives better context on this. Hawkins notices that Drake has been acting strange which makes Hawkins suspicious.
THIRD PART
The final part of my theory which brings us to the overall conclusion. Everything before was so that I can fit the timeline properly and match all the events.
Let’s jump back to chapter 956 again. By now the Kaido-BM fight is resolved and all the SH have regrouped following the event of Drake's conversation. But now we'll look at the most important piece: Blackbeard
So basically, Blackbeard the moment he heard the news of Warlord abolishment he went after Hancock to take her fruit.
Now if the news of abolishment had already been revealed or hinted in the newspaper back in Chapter 925 like I've seen some people say, Wouldn't Blackbeard immediately go after Hancock as soon as he heard the news to not let Navy capture her so he can have that power for himself? It would be stupid if he didn't and BB is too smart not to capitalize on that.
But he didn't move till the reveal of the warlord collapse in 956. And Perona was also reading the newspaper in 925 but she also didn't comment on anything regarding that.
I genuinely think Mihawk's specialty might be observation haki.
Let me know what you guys think about this theory. Is it trash or is it good?
