‘Chicago Fire’s Casey & Brett Check on a Couple After a Call (VIDEO)

Following their conversation about Firehouse 51’s tendency to follow up on calls, Chicago Fire‘s Casey (Jesse Spencer) and Brett (Kara Killmer) are doing just that in Wednesday’s episode.

TV Insider has an exclusive sneak peek of the two of them stopping by Med in “A Chicago Welcome” to see how a couple is doing after saving them from a fire earlier in the day. As Brett noted in the January 15 episode, “one of the first things you learn at the academy is you get the victim to the hospital best you can and you don’t look back, that it’s the only way to survive mentally.” The members of this house don’t do that.

Watch the clip above to hear the Larsons’ sweet story and watch Casey ease the man’s concerns.

“We’re not rushing into it very quickly,” Spencer said of the Brett and Casey relationship. “The slow burn is the perfect way to play this.”
