Dr Natalie Manning and Dr Will Halstead have had a complicated relationship right from the first season of 'Chicago Med'. It seemed at the end of Season 4 that it was all going to be okay. But an accident causes Natalie to lose her memories, which in turn gives her then-boyfriend, Phillip, to lie to her that she is engaged to him in the Season 5 premiere episode.

However, as time went on, Natalie did not feel right and eventually broke it off. Will always suspected something was off with Phillip, and by the time he finds the truth about Phillip's fake engagement, he goes to tell her. But Natalie has had enough of the men in her life and yells at Will to leave her alone.

After that, the two have been mostly ignoring each other, but it looks like it will all come to a head in the Season 5 midseason finale as Natalie's memories and feelings of Will start to come back. But Will has been taking measures to move on, so will Natalie be too late?

Meanwhile, in a sneak peek, we see that Phillip's daughter, Sophie, is in the hospital. But Natalie can't find Phillip, who has called his sister and brother-in-law to inform them about Sophie. Phillip's brother-in-law says he is a "pathological liar" and that he left Sophie. What will happen to Sophie now?

Elsewhere in the episode, the synopsis suggests that April Sexton receives unfortunate news that makes her question her future with Dr Ethan Choi. This could be about their future of having children as Ethan seems really eager to start a family with April. Tension might already be brewing since it looks like April might have some unresolved feelings for Dr Crockett Marcel.

But it looks like that may not be the only bad news viewers will get as the synopsis suggests that Dr Charles and Maggie face some tough times on the horizon. Maggie, as well as Caroline, Dr Charles's wife, are both battling cancer and it looks like the midseason finale will make things take a turn for the worse.

The Season 5 midseason finale of 'Chicago Med' will air on NBC on Wednesday night, November 20.
