* BigNo: [[spoiler: Merlin in the cavern]].
* BitchInSheepsClothing: [[spoiler:Eira]]. [[SarcasmMode Aren't you glad]] that even in the show's penultimate episode, the writers ''still'' found a way to shoehorn in one last evil woman to betray our manly heroes?
* BondVillainStupidity: Let's see, your archenemy is [[spoiler: basically defenseless and what do you do? Kill him now that he can't fight back? No, that's stupid, trap him in a cave where he can regain his magic!]]

* [[spoiler: ButterflyOfDeathAndRebirth: In a sense, Merlin conjuring the butterfly, showing that his magic is back.]]
* CallBack: Merlin sees several images from past episodes while gazing in the crystals. [[spoiler: His ability to communicate with Arthur telepathically also comes back.]]

* LastEpisodeNewCharacter: Eira

* MagicStaff: [[spoiler:Merlin walks out with one after meeting his destiny.]]
* NiceJobFixingItVillain: [[spoiler: Nice job locking Merlin in the caves, Morgana. It's not like you know he came to that ''specific'' place to regain his vast magical powers or anything. While we're at it, nice job depowering him and necessitating his journey to those caves in the first place, ultimately making him ''even stronger''.]]
** [[spoiler:Though Morgana and Mordred can be reasonably excused as not knowing this particular property of the cave, it's also a scrying cave which can show the past, present, and future. Hence, showing exactly when and where Morgana's going to attack and giving him the ability to warn Arthur.]]

* RousingSpeech: Arthur to his men. [[spoiler:Balinor]] to Merlin.

* ShoutOut: The magic-eating slug may look like something out of ''{{Franchise/Alien}}'', but is in fact a reference to ''Literature/TheLostYearsOfMerlin''.

* [[spoiler: SoProudOfYou: In contrast to Arthur's encounter with Uther, Balinor is very proud of Merlin.]]
* SuperMode: [[spoiler:The eventual result of Merlin meeting his destiny.]]

* TrueCompanions: [[spoiler: It doesn't matter that Arthur doesn't know how Merlin contacted him... the fact that it was Merlin was incentive enough for him to rally his army.]]
