User blog comment:The Purple Orange XD/What do you want in RTTE season 4/@comment-27609869-20160716233444

- Viggo is obviously gone by the time of HTTYD 2. Maybe Hiccup will turn his brother against him since Viggo always belittles and looks down on him. Ryker seems to be more open to being manipulated. - It's been hinted that this lense might help her find her tribe, thus be used as an exit for her character. It's strange how none of the characters have noticed it though.

 - Heather should leave early in S4 if the show is planning to end where HTTYD 2 begins. Heathlegs' break up will be a result of Heather leaving the Edge. Ruffnut might comfort Fishlegs in the aftermatch, which might lead to Fishlegs developing feelings for her.

 - Hiccup and Astrid's secret could be two things:

 1) Their relationship. Art and Doug have said that they are going to show the other teens finding out about their relationship. This means that Hiccup and Astrid will try to keep it under the wraps.

 2) Dagur is alive. Dagur's voice actor David Faustino recently hinted that Dagur might be alive after all. Maybe Hiccup and Astrid have to keep this fact a secret for some reason.

- The Edge is definitely going to disappear. It's not on Hiccup's map in HTTYD 2, and some of the staff from RTTE said it was going to be destroyed along with every other non-movie element.

- They will probably develop Mala more in season 4.
