merlin and arthur (+ maybe one knight) go on a brief, supposedly easy mission
they end up in a small, confined space and a random person just pops up out of nowhere. random person turns out to be a druid
random druid: *ranting about the prophecy and all that shit*
random druid: *mentions in passing that emrys is immortal*
merlin: wait, emrys is immortal?!
random druid: emrys literally means immortal lol
arthur + knight: *intimidates random druid so they leave*
merlin: *crashing out and hyperventilating in the corner, staring into space w/ tears streaming down his cheeks*
arthur notices merlin is freaking out and goes to him, also slightly panicking
arthur, holding merlin’s face: what’s wrong?!
merlin, numbly staring into space: i’m going to watch everyone i love die.
so basically emrys reveal + merthur
