User blog:Mr. Nightingale/Is there hope in Once Upon A Time for HTTYD?

I just finished watching the new episode and I saw something in the next promo that caught my eye. On a piece of paper that one of the characters unrolled the text appeared to be in the same dilalect as the Vikings from HTTYD.

THe other thing I noticed was that could also support this was that the character who was in the promo was in a foster home with only two other children at the moment.

Just saying that this is all just speculation and it could all just mean nothing but let me know what you guys think.
