First, they are two different castles (“Journal” covers building the Castle of the Two Sisters, this comic is about building Canterlot Castle, which fits that it takes place after Luna got her cutie mark). Second, it’s all moot since the Season 7 finale (which these comics were made to tie into) made “Journal” canon discontinuity (making everything else about it, like Luna and Celestia being born alicorn, debatable) by revealing the Tree of Harmony was grown during Star Swirls absence, as opposed to him showing the princesses the Tree in “Journal”. Said finale also retcons anything else “Legends” seemed to contradict, so Jeremy Whitley was following canon after all.

Both stories doesn’t make sense with the story of Princess Platinum…

Remember: the one being built in the comic is Canterlot Castle, not the Castle of the Two Sisters.

oh come on! we’ve seen you walk right up to a horrible manticore like it was nothing!

There’s two possible interpretations I can see:
 

@Esteban  
I think they would also be pretty surprised if she foaled on the Moon regardless.

@TexasUberAlles  
And how does a specific location change anything? They shoudn’t be suprised at all whether Cadance give birth to an alicorn on either Equestria, Dragon Land or on the Moon.

@Esteban  
suprised that there could be a natural born Alicorn  
This was addressed about a million times when the episode first came out; they weren’t surprised that an Alicorn was born, they were surprised that it happened in Equestria.

@Deserter  
Most dissapointing thing is that Jeremy Whitley actually read the Journal as seen in his Sombra arc. So he retconned all of it on purpose.

There is nothing left of Faust lore, it seem. I was already afraid that Haber erased that influence when he made Luna and Celestia suprised that there could be a natural born Alicorn.

@soundtea  
Sounds like they confused Torch and Garble.

They are talking about two different castles ones the castle of the two sisters and ones the Canterlot Castle.

@soundtea  
The book has descriptions of the characters. For some odd reason it gets lots of points wrong or come out of nowhere. Like how Chrysalis was corrupted in her quest to search for the power of love and was tried to be convinced to stop being evil by Twilight, while Torch was stated to be flat out evil.

@soundtea  
Ok I’m curious. What did they do to Torch?

@Deserter  
The new EoH volume 2 book has plenty of problems too. Notably Torch is apparently pure evil now.

Yeah, IDW does have a problem with cross-merchandise continuity, you just realized this?
