It is Gwen who is the bravest of them all. She has no magic to rely on yet she’s stood up to powerful men: Uther, Arthur, Cendred, Agravaine and Helios despite the danger to herself. She defended the memory of her father whilst facing certain death. Raised the alarm when Camelot was in danger from Helios. Saved Merlin by attacking a Lamia and even though she knew Arthur may not have allowed her to stay in Camelot she took up arms to help free Camelot from the grip of Morgana and Helios.
Guinevere is the female bamf of the show. Her actions are proof of that.
I agree. I wish we had more Gwen storylines. She was great with Gaius!
