[Rei lets out a long, slow breath, leaning forward and moving her hand up to grip Merlin's shoulders. Loneliness is a powerful emotion, one she knows all too well.]

It was lonely at first, for me too. I...when I was a child, I could always do things, see things other people couldn't. But then I found my people, the other guardians. And we connected. Became friends.

[And then she wasn't lonely anymore.]

You'll get there. Arthur will understand, one day. I know it, in my heart I know you're not going to be alone forever. [He's too likable. Too friendly.]

And you're definitely not alone here.
