"I can't tell you about shocking deaths. I can't say," he confessed, "but I will say it gets crazier. That was really like icing on the cake. It gets crazier."
Viewers saw Hodge's character, Noah, separated from Rosalee (Jurnee Smollett-Bell) last season as he was caught and put in prison, and while Hodge stayed mum whether the pair would reunite on screen, he revealed that they'll definitely "fight" to get back to each other.
"I will tell you that they fight really, really hard to get back to one another. Whether it happens or not, we won't really know for some time," he said. "They are on their own individual journeys right now, discovering new things about themselves."
"We've seen Rosalee grow from this quiet, meek person to now this soldier," he continued. "You'll see Noah grow from this headstrong fighter and rebel to understanding what it really means to be a leader and coming into his own as a man this season. Will they fight like dogs to get back to each other? Yes!"
The two may be separated, but Hodge said Noah's love for Rosalee won't fade -- it's a "real love."
"For me, personally, I feel like this is really Noah's first time being in love. Real love. So going into this season they've established that bridge and that bridge is never broken, even in their absence," he explained.
As for that scene where Noah looks like he's crafting an engagement ring in prison -- Hodge did confirm that his character was making jewelry... but just wouldn't say what.
"You're trying to get all the cookies out of me! He was making what looked like a ring of some sort. I can't say if it's an engagement ring or not," he teased. "All I can say is that they did really have me twist that metal and it took a lot of fortitude."
And while Hodge isn't quite ready for marriage himself, he did reveal that he's single but "thinking about someone I'm interested in."
"She's very intelligent. She's very creative. She's intellectual," he gushed. "With her talent, her skills and her intelligence, and what she's done in her life, I see there's a deep counterpart to where I'm at and where I'm trying to go."
Season two of Underground premieres Wednesday at 10 p.m. ET/PT on WGN America.
