Tamlin is one character from Sarah J Maas A Court Of Thorns And Roses series thats awaiting a redemption arc, and this mate theory could be the missing piece that propels him forward in the best-selling series. The upcoming sixth book in the A Court of Thorsn and Roses universe is likely to explore fresh relationship dynamics between various characters, including Tamlin and Elain Archeron (whose romantic storylines have been left open-ended). Foreshadowing throughout the series, from the first book, to A Court of Silver Flames, suggests Tamlin and Elain have deeply ingrained similarities, making a strong argument that they are mates.
