Watch a sneak peek for tomorrow night’s Merlin episode “With All My Heart,” in which Arthur and Merlin see something terrible in the forest.

It seems like Merlin will be picking up the pace for the final batch of episodes before the end. “With All My Heart” is the fifth to last episode of the show, and in this sneak peek we see Arthur discovering the truth about Gwen and Morgana’s alliance:

Poor Arthur, right?! It seems like everyone he loves is betraying him. He seems ready to end it all right there, but Merlin promises Arthur that Gwen is under the influence of Morgana’s magic and can be turned back. And with Merlin’s help, surely Arthur will get Guinevere back… or will he?

Merlin 5×09 “With All My Heart” airs tomorrow night at 20:00 GMT on BBC One. Don’t forget to check out Hypable’s Merlin podcast Talks of Camelot for discussions about each new episode as they air!
