NBC’s “Chicago Med” left fans with several cliffhangers at the end of last season. One of the most shocking twists of the season finale was Nurse April Sexton’s discovery that she has tuberculosis. Will she tell her boyfriend Tate Jenkins about it in Season 2? More importantly, will it ever be contagious?

April (Yaya DaCosta) is going to have a huge storyline in the upcoming season of “Chicago Med.” The medical drama’s executive producer, Diane Frolov, revealed to TVLine that will have a long arc that revolves around her current health crisis. According to Frolov, in the Season 2 premiere, “She’s really avoiding Tate and his son because of her fear about giving TB to them even though she is latent. She has to be really convinced that she’s not contagious and can continue with her life. But as she does so, her TB ceases to be latent and becomes active.”

An active TB is certainly going to affect her relationship with Tate. But will he find out eventually? Looks like the couple is going to be really teased in Season 2.

Apart from the nurse’s storyline, episode 1 will see the introduction of Dr. Rhodes’ (Colin Donnell) new mentor after Dr. Downey (Gregg Henry) breathed his last. This new and challenging mentor, Dr. Latham (Ato Essandoh), will prove to be quite difficult for Rhodes to handle in Season 2. But the handsome doctor must complete his fellowship.

The Season 2 premiere of “Chicago Med,” titled “Soul Care,” will also show Dr. Manning (Torrey DeVitto) take on an interesting case. She will treat a pregnant woman who was also a victim of a high speed collision.

Meanwhile, Dr. Ethan Choi (Brian Tee) will be promoted to the challenging position of Chief Resident.

“Chicago Med” Season 2 premieres on Thursday, Sept. 22 at 9 p.m. EDT on NBC.
