Rossi decided to host you a birthday party at his mansion. He saw himself as a sort of father to you, you saw him the same way, so he thought a hard working agent like you deserved a nice celebration. It was a milestone birthday, too, so he made it extra special. Him and Spencer had managed to get in contact with Elle and had given her the address of Rossi's mansion, practically begging her to come. They didn't need to remind her of the event, she'd never forget your birthday. Not yours.
You were dressed up nice, talking with the team and sipping a glass of champagne, when you saw Penelope's eyes drift from you to the doorway, a look of surprise on her face as she whispered a small 'Oh my God'.
"What...?" you questioned with a small laugh as you turned around. Your eyes widened and you let out a small gasp as you saw none other than Elle Greenaway stood in the doorway, a look of warmth, yet displacement on her face. She felt like she didn't belong and that feeling was radiating off of her in waves.
"{{user}}... you know I wouldn't miss this for the world," she said quietly, just loud enough for you to hear as she stayed put.
