When "Chicago Fire" returns after the conclusion of the Sochi Winter Olympics, Dawson will get closer to her new teacher, Severide. 

Dawson (Monica Raymund) and Casey (Jesse Spencer) are currently together, but Dawson will soon confide in Severide (Taylor Kinney) about Casey. Could Severide get in the way of Dawson and Casey's relationship?

"We really get close," Monica Raymund told TVGuide. "I need him [Severide] and he's there for me and we have this... truthful moment where I don't want to admit something to him and he just gets it and he takes me out and brings me to the firehouse to cheer me up." 

While fans won't know what happens until the show resumes, there are a series of Dawson-centric websiodes to tide fans over until the series returns next week. 

The webisodes, which debuted last week on NBC.com, are a series of four installments that chronicle Dawson responding to an emergency when she is the only one at Firehouse 51. 

"Somebody's hurt in this car accident down the street, and there's nobody around so ... I'm the only person around to help the guy," Raymund said. "I have to help this guy get out of the car before it blows up."

She said she was "humbled" to get the call from the producers about filming the webisodes. 

"I'm very flattered. I'm pretty up for the challenge," she said. "I love the show. I love representing women on the show, and hopefully female firefighters, so any opportunity, I'm going to jump on it."

Raymund also said she got the idea for her character to train to be a firefighter when her character helped Casey (Jesse Spencer) deliver a baby in the middle of a car pileup. 

"I became very compelled with the physicality of it and especially ... I think just the extreme challenge of what that would be," Raymund said. "I am simply insatiable. I want to try everything once."

Raymund said she had to do intense training for the upcoming firefighting test, which included strength training, heavy cardio and mask training. 

"When we were first training with the masks, I had a really hard time," she explained. "I have a little bit of anxiety disorder so I can get panic attacks now and then, and claustrophobia is one of the triggers of that," she says. "I'm trying to feel like a total badass and inside, I'm absolutely dying."

While Raymund made it through the training, her character still has to tackle her biggest challenge yet: her relationship with Casey. 

"I think he's scared of me becoming a firefighter. Why? Because it's extremely dangerous. It's a job of life or death. it's that element that I think really attracts Dawson to him even more and proves his love for her, but then there's another element to the conversation where I'm a woman, and he might see me as potentially in harm's way, but who's to say that I'm not as capable as Casey or anyone else," she said. "That starts to permeate within her relationship."

While she said that viewers will see Dawson take the official firefighter's test, Raymund said viewers may not know until next season whether her character will become a full-fledged firefighter or go back to being a paramedic. 

While the webisodes mostly focus on Dawson, the first and last installments will include Cruz (Joe Minoso), Mouch (Christian Stolte), and Hermann (David Eigenberg). 

Regular episodes of "Chicago Fire" return on Tuesday, Feb. 25 at 10 p.m. EST on NBC.
