Kim and Adam are getting ready for work.

They weren't exactly aware of Erin's secret.

Truth be told, She was pregnant with Quadruplets when she left Chicago 8 years ago, and the babies father was Jay Halstead.

Their names are Cadwell Lindsay-Halstead, Kayden Lindsay-Halstead, Ginerva Lindsay-Halstead, and Eartha Lindsay-Halstead, and they are sweet kids.

They don't want to meet their daddy at all.

Kim said," Who's going to watch Jay for us?

Adam said," Izzy will watch Jay for us, babe.

Kim said," Alright, babe. That works for me.

Izzy arrived at their house, and Adam lets her inside, and they head to the school to drop off Maklya and Michael drop Jerry Burgess-Ruzek, Britney Burgess-Ruzek, Andy Burgess-Ruzek, and Sarai Burgess-Ruzek off at daycare, and then they head to work and park their cars at work.

They head inside the police district to see Trudy Platt calmly talking to a candidate for not doing their job correctly and head upstairs while shaking their heads.

Kevin is there with his wife Vanessa Rojas, and their babies Veronica Rojas-Atwater, Willa Rojas-Atwater, Malik Rojas-Atwater, and Kyle Rojas-Atwater, are in Daycare too.

Erin arrived, and she looked so exhausted.

Kim asked," Erin, are you okay? Are you not feeling well? Do you need some medicine?

Erin said," No, I'm fine. Just had trouble getting to sleep. I was nervous about today.

Kevin said," Don't be so nervous. We got you.

Erin said," Thank you, Kevin. I appreciate it.

Hank said," Everyone, we have a case. 4 kids are missing. Names are Cadwell Lindsay-Halstead, Kayden Lindsay-Halstead, Ginerva Lindsay-Halstead, and Eartha Lindsay-Halstead, and they are 8 years old.

Erin tensed immediately after hearing her kid's name and started packing like crazy.

Everyone noticed and asked questions about why Erin was acting worried about the 8 year olds for. They shrugged it off for now.

Hank said," We find to tell their mom, and hopefully, she can help us find her kids.

Erin said," Hank, there's no really need to contact the 8 year olds Quadruplets mom.

Hank said," Why would you say that, Erin?

Erin shouted," BECAUSE I'M THEIR MOM.

Edita Parker, Rachel Parker, Zoey Marcel, Nancy Becker, Mary Castro, Stella Shore, Kim Burgess, Vanessa Rojas, Megan Shay, Celine Conte, Mila Cruz, Joanna Vincent, Gianna Voight, Edita Parker, Rachel Parker, Emma Sexton, Leilani Severide and Penny Casey, Nelson Maximoff, Sean Roman Antonio Dawson Adam Ruzek, Kevin Atwater, Josh Parker, Terence Olinsky, Milani Rhodes, Paul Choi, Dante Torres, Henry Allen, Vlad Zvonecek, Nick Parker, Malcolm Lockwood, Galvin Resse, and Christian Vincent stare in shock at her.

What was going on here? If they were Erin's kids and she gave birth to them, then who were the Quadruplets biological father?
