It is currently unknown who is responsible for penning the premiere, but Adam Glass ("Bad Boys," "Mother's Little Helper") has revealed that he will be writing one of Team Free Will's early season 10 adventures.

Unfortunately, Glass' script may not involve too much Cas (Misha Collins), although he is hoping to have a chance to write the angel's lines soon.

"I have not written Cas in a bit but would love 2 tackle him in a #supernatural episode this year. I think of him often," Glass wrote on Thursday.

However, those viewers who miss the adventures of the Winchester's early days and are looking for some information of the pair's tumultuous relationship may be rewarded by Glass' upcoming work.

"We can pitch anything but I prefer MOW and boy melodrama stuff. My fav #SPN seasons are 1-3 and I try 2 write that," Glass tweeted https://twitter.com/AdamGlass44/status/477170919845003265 on Thursday.
