Not really, no. The only two flags for Seymour (other than specific choices made at various points) are Lena's disposition towards him, and Lena's sexual attraction. Other than that, there's simple relationship score, like with any other character. It's used mostly interchangeably with Lena's disposition, and reflects more Lena's opinion on Seymour, than the other way around.There is AFAIK also a variable which is for how much Seymour likes Lena. Seymour can get smitten by her.
