Spoiler alert: This post contains a plot from the series finale ofShadowhunters.

AlthoughShadowhunterswas given anextended series finaleby Freeform, that news came after the beloved fantasy series wascanceled after three seasons.

“We never would’ve killed the Seelie Queen this early,” Todd Slavkin tells EW.

“That relationship between Jonathan (Will Tudor) and the Seelie Queen was going to be a season.

It was going to be much longer.

His metamorphosis was going to take more time.”

“The Helen and Aline relationship was going to be big moving forward,” Slavkin says.

“Helen Blackthorn has siblings.

“We would’ve planned the wedding,” Slavkin says.

“That would’ve taken time.

The wedding would not have happened the same day.”

Two other stories that would’ve gotten more play?

Maia (Alisha Wainwright) as an alpha and Luke (Isaiah Mustafa) as a Shadowhunter.

“Luke as a Shadowhunter was going to be a great story,” Slavkin says.

Then there’s the question of Simon and Izzy.
