Lost 3x21 - full reaction (Patreon)

Hey guys! Someone on youtube mentioned that i should be watching something called lost the missing pieces before i start s4. Just wanna make sure that's the correct order to do it, because i have the files on my season 4 dvd extras folder, which would suggest i should be watching after s4. Please let me know of the correct order and in the meantime enjoy this reaction :)
