Legends of Tomorrow’s Victor Garber, who plays Martin Stein and is one half of Firestorm teased the upcoming Arrowverse Crossover.

In an interview with Digital Spy, Victor teased a number of revelations about how Martin will behave in Season 3 and how his relationship with his daughter will develop.

A lot goes on – in his real family life, and his family life on [the Waverider] and he has to choose some things and make some decisions. Martin is questioning everything in season 3, which I think is very appropriate – for someone of my age and also of Martin’s temperament.

He did note that his relationship with his daughter, Lily, will be further explored this season.

I’m not well-versed in this world that I’m inhabiting – so the most interesting part for me is the human connection. For me, it’s all about what happens between people and so when they introduced Lily, I was very happy about that… and continue to be. There’s a lot more going on this season, that I’m probably not allowed to speak about, but it just gives me something to do. Other than talking about physics – which I don’t understand at all, by the way!

Along with dropping a few teasers for the upcoming Legends of Tomorrow Season 3, he also expressed his excitement for the Arrowverse crossover. He’s really excited to work with Supergirl’s Melissa Benoist.

I’m in love with Melissa [Benoist], who plays Supergirl, and I haven’t really had much to do with her at all. But when I’ve just been in the room with her, she’s just so enchanting.

However, despite his excitement he did not how grueling the crossovers can be when it comes to scheduling and making sure everybody is where they need to be.

I’m excited about all of that… As exhausting as all of that is [crossing the shows over], and very disruptive to schedules – because everybody’s trying to figure out how they’re going to shoot their episode that week – it turned out to be a lot of fun.

The CW is keeping a lot of the details mum on the crossover event, but given Victor’s excitement it looks like it might be even better than last year!

DC’s Legends of Tomorrow makes its fall premiere on Tuesday, October 10. It debuts right after The Flash.
