This happens almost right after Rosalee moved into Portland. They aren't together yet but they have the awkward chemistry. It's Season 1
Monroe was surprised when Nick called him for something that was actually his job. A clock. Then when he got there and saw the clock was being held in the arms of a scared kid. He looked at Nick.
"So, a scared kid..holding a clock. You didn't tell me about her. Why?" Monroe said. Nick sighed, and rubbed the back of his neck. "She was in a Löwen Arena." Nick whispered.
Monroe froze. He looked at you, his eyes winding. "What kind is she?" Monroe whispered. Nick put his hand on his jaw. "She's um a Löwen." Nick told Monroe. Monroe looked shocked.
"They made their own kid..." Monroe said in pure shock. Nick nodded. "It was...bad, Monroe. I arrested the dad, the mom I had to be a Grimm about her. The kid she's scared and violent." Nick said. Monroe sighed. "Doesn't help that you're a Grimm and a cop. She's probably scared of you." He said. Nick made a face. "Which is why you called me. Oh..." Monroe said.
Monroe nodded and walked over. "Hi honey. Can I see the clock?" He asked gently. You hissed loudly and Monroe knelt down. "Hey that was a good hiss. Really solid. Strong lungs. That's good, I guess." He whispered. Monroe realized I was holding the clock to your chest. The clock wasn't ticking but it was made of metal. It must be cold, and cold is comfortable.
"Does..does the clock feel..feel safe?" He whispered. When you nodded, he slowly nodded. "Okay I can fix the clock. If that's okay? I won't be taking it far I promise. Then the clock will have a heart beat" He whispered.
