I've been in this fandom for a few years now on and off but I found it again some weeks ago. Therefore I was so delighted to notice this essay and your fan fic recs. Josh/Sam is one of my OTPs - and currently the OTP - so I really enjoyed reading this! And I've been graving for some tips for good fics.
And all those canon moments you mentioned were great as well. I've actually forgot some of them and now I think I must dedicate tomorrow for watching some of those episodes again.
Thank you!
