He gets woken up by Millie jumping on him and licking his face— it seems to be a routine that she's gotten into in the last few weeks, whenever he spends the night. He gently pushes her off of him and opens his eyes to find that Erin isn't in the bed with him anymore, but then he hears the shower running in the bathroom. Millie licks his cheek as he reaches for his phone to check the time; a smirk coming to his face when he sees that they still have two hours before their shift starts. He gets out of bed, not even bothering to cover himself as he pads over to the bathroom. He walks over to the tub, pulling the curtain back and stepping in behind her as she rinses the shampoo from her hair.

"Mmm." She hums as he wraps his arms around the smooth, wet skin of her waist and places kisses from her jaw to her collarbone. "Did I wake you?"

"No, your puppy did, again." He mumbles against her neck, and she giggles.

"She's never done that to me."

"I guess she just likes me more."

"You wish." She mumbles as he uses one foot to spread her legs, positioning himself at her entrance. He groans and she gasps when he enters her with one push. She places one of her hands on the tiled wall, and the other lays on top of his on her stomach.

"Come on Millie." Otis cheers from down the hall, kneeling next to Matt, Gabby, Capp, Cruz, and Stella.

"Millie come here girl." Stella says next, holding a treat out in front of her. Jay walks into the hallway and wonders what the hell his co workers are doing. His eyes meet Erin's as she stands in front of the kitchen with Millie lying by her feet. He puckers his lips quickly and winks at her before raising his eyebrow and pointing at the six people on the floor in front of them.

"What are you guys doing?" He asks as he gets closer to them; Millie lifts her head, then gets up and runs over to Jay, avoiding the small group on the ground to get to him.

"Trying to get Millie to come-" Gabby starts but stops herself from finishing the sentence when she sees the puppy run right over to Jay. He sets his bag down on the floor as he scoops up the not-so-little puppy. She attacks his face with kisses and everyone including Erin laughs. Erin stays in the same spot she's been in for twenty minutes as their friends get up and walk to either Jay or her. Gabby and Stella go over to Erin, and they smirk as she looks down as if she wasn't just making googly eyes at Jay.

"So much for no in house romance." Gabby states.

"What are you talking about?" Erin questions.

"You don't actually think we don't notice the little touches and longing looks between you two, do you?" Stella asks.

"Is it that obvious?"

"Yes." Stella nods. "Plus your puppy kind of gives it away."

Erin laughs at that. "She's obsessed with him." She admits.

"It wasn't obvious until a few weeks ago, but now it totally is." Gabby adds. "Also if you want your secrets kept you shouldn't tell Kim."

"That wasn't at all intentional, we just bumped into her at his friend's bar one night."

A call comes through and everyone rushes out to the garage; Erin and Gabby hop up into the ambulance.

"I knew you wouldn't be able to resist him when I saw you eyeing him up on his first day." Gabby says as they are pulling out of the garage and Erin just smiles.

When they arrive to the address, they see the house in flames and a woman pacing back and forth on the sidewalk with a toddler on her hip.

"My daughter, you have to go get my daughter!" She screams as Jay and Kelly get out of the truck first.

"Where did you see her last?" Kelly asks, as Jay puts his mask on and runs towards the house.

"Upstairs, in her room." The woman answers, and he goes to follow Jay in. They move through the house swiftly, getting to the little girl's room quickly.

Jay hears coughing and moves towards the closet. He opens the door, and sees the little girl curled up on the floor. "Kelly I got her." He yells as he picks her up and wraps her in his coat before exiting the house.

He takes her straight to Erin and Gabby, and they give her oxygen.

"Where's Daisy?" The little girl asks Gabby.

"Who's Daisy sweetheart?" Gabby asks.

"My puppy." The little girl coughs.

"Jay!" Erin yells, and he looks over at her. "Did you see a dog?"

"No." He yells back.

"Can you go look?"

"We'll go look once the flames are tamed."

"Jay." She says after he turns his attention back to the fire.

"Fine, I'll go get Daisy myself." Erin mutters, and that gets his attention.

"Like hell you are, the house is falling apart." He scolds, as she shrugs her shoulders and runs up to the house.

"Erin!" Jay and Matt both yell. Jay goes to run in after her, but Boden puts his hand up, just as the flames roar louder and grow larger.

"You're not going in there." Boden orders, and Jay pushes his hand away. "Halstead!" Jay continues to ignore his boss and rushes into the house.

"Erin!" He shouts as he walks towards the back of the house. "Erin!" He continues on the first floor, and then he sees her. She's on the ground; her eyes are closed and the puppy she came in for is snuggled to her chest. There's a wooden beam pinning her to the floor. "Damn it Erin." He mutters as he quickly removes his oxygen mask and slips it over her head. He takes off his coat to lay over her before moving to lift the heavy beam. The flames close in on them and his arm gets burned, but the adrenaline coursing through his veins blocks out the pain, helping him focus on lifting the couple hundred pound beam off of Erin's limp body. Once she's freed, he picks her and the dog up and maneuvers through the hall as the house starts to crumble around them.
