Hi, first the General search

1. I was reading Astolat's fic Sumer is icumen in and was wondering if there were any fics with a similar plot, where Sam and Dean start off as brothers and later realise they are NOT related. I would like it to be Sam/Dean in the end but them just being able to aceept who they are enough.
(I like happy endings)
The specific searches

2. Jensen is a mad scientist who is also an evil overlord, who kidnaps Jared, the freedom fighter. What I remember about the story specifically - something to do with crystals. Jensen's powers are crystal related and if he doesn't have that in his system he is basically a nice guy. I think it was a WIP. Lost the link, want to know if it has been updated.

I would welcome anything with a similar plot so please rec.

Thank you in advance. Hope I got the tags right.
