Hi everyone, I recently bought some carbon steel pans and have gone through the whole seasoning process with them and have cooked \~10 times with this specific small pan. Yesterday I made the big mistake of setting it on medium-low on a small burner to dry it out, and then giving it a light oil dusting (advice I learned from lurking here). Unfortunately, excuses about my bad sleep aside, I got distracted and left my kitchen to work. I came back to my kitchen 3 hours later and found that I had not turned the burner off. Now I'm worried about what I have done to this pan and what can be done to fix it. I am aware that the blue color is the polymerization of the oil that was seasoning the pan, but I'm sure that the rust-like staining is not a good thing to leave on and 'just keep cooking'.

It does not seem as heavily burnt as some pans I have seen online and does not seem to have warping issues, most likely due to the lower heat, so I am wondering if any of you have any tips to fix this aside from scraping down with chainmail and water and going through the seasoning process again. I am trying my best with these pans and am beginning to love them, so bear with my amateur error here.
