In a new interview, Merlin actor Colin Morgan teases series 5, and a pivotal moment surrounding Merlin’s magic. Beware of mild spoilers.

Speaking to SciFiNow magazine, Morgan enthuses that the fifth season is the “the Merlin I’ve been waiting for.” He calls it the most ambitious, as the writers have pushed the storyline forward a few years, and in his words, “pushed the characters into manhood.”

Teasing how this year will be different from the last, Morgan says:

We left Merlin at the end of the last season tipping over into a darker side, and I think that’s a reference for me for the rest of this season. I think he is so confident in himself now, and in who he is and what he is destined to do. He has a resilience and power that drives him for this season. He gives as good as he gets.

He also teases “one of the most important scenes there has ever been in terms of Merlin’s magic.” He says:

Arthur is forced to confront magic a lot in this series, and that could change everything, for Merlin and for everyone.

Do you think Arthur will finally discover Merlin’s secret?!
