Being the new kid in town is hard. Being the new kid in town when you're used to living in 15th century Europe is the actual worst. That's the life poor Sebastian (Thomas Doherty) is living this season on Legacies, though.

We first heard of this enigmatic new time capsule vampire when Julie Plec told TV Guide about a new vampire who just so happened to get desiccated as a teenager centuries earlier. The supernatural rules regarding that particular predicament can be hard to understand, so to a newbie like Thomas Doherty, who had no prior experience with The Vampire Diaries universe, it was extra crazy to step into Sebastian's shoes.

"I had a friend who is a male, and who is 24-years-old, and he was watching The Vampire Diaries... and he encouraged me to watch some," Doherty told TV Guide. "So I did watch some of that and I can see how people get so hooked on it. It's so entertaining. But then obviously when I got this, I did my research and I watched some Vampire Diaries, I watched The Originals, and then obviously caught up with Season 1 of Legacies. And yeah, as I said, it's so addictive!"

Doherty isn' the first innocent soul to be sucked into the addictive world Julie Plec created, and he won't be the last, but it's good to know he did his homework — especially considering we're still so in the dark about where Sebastian came from. We have very few clues to work with so far, but Doherty revealed that we'll get some answers in Episode 5 of this season.

As for now, we'll have to settle for more simmering scenes with Lizzie Saltzman (Jenny Boyd), who Sebastian has already begun seducing. And even though their scenes together have already made shippers everywhere sigh with longing — Sebastian practically stepped right out of a romance novel, can you really blame them? — we've still got our eyes peeled for any clues that he might have ill-intentions towards the witch. According to Doherty, there's more going on there than we might expect, but it might not be as nefarious as we worried.

"Sebastian's initial attraction to Lizzie, that initial spark, does come from a past lover that Sebastian has had," Doherty said. "So that's a little bit of his background... I do think it is genuine, and I do also think that Lizzie does remind him of a past lover. She's very intriguing to him, and he wants to know more about who this girl is."

Poor guy, he might just be hurting over a lost lover from centuries ago. In that case, Lizzie sounds like the perfect girl to help heal those wounds.

Unfortunately, this relationship might have its fair shares of ups and downs. Jenny Boyd called it a lust/hate relationship and seemed to think Sebastian could be the new Damon Salvatore. Doherty, on the other hand, made another, just as juicy, CW comparison when it came to Sebastian and Lizzie's romance.

"I always say, it's a bit like Marmite, you love it or you hate it, and that's Sebastian," Doherty said. "I think it can be similar to something like Chuck (Ed Westwick) and Blair Waldorf (Leighton Meester) in Gossip Girlthat kind of tense friction kind of relationship, but highly entertaining."

If these two are anything like Chuck and Blair, they've got a long and complicated romance ahead of them that may or may not end in tears. Either way, we're definitely along for the ride!

Legacies airs Thursdays at 9/8c on The CW.
