Rossi x fem!teen reader

Imagine: the team coming over to the mansion for dinner made by Rossi but also get a show
⚠️trigger warning brief talks about suicide⚠️
The team had all arrived just to the mansion. Walking in the different smells immediately hit their noses. Entering the kitchen they can hear soft Italian music playing in the background. Rossi (some how sensing them) turns around to greet them and dinner is just about done. When he is cut off by the sound of an electric guitar. The team got spooked by the sudden noise and looked towards the stairs where the melody came from.
They all looked at Rossi for answers while he just smiled with a sigh and shook his head. "Well looks like we get a show before dinner" He mused.
"Is y/n playing that?" Hotch had been the one to ask shock and awe clear in his voice.
"Yeah, n/n took it up when things started getting hectic to take her mind off of things" Rossi didn't want to specify what you had been going through because it simply wasn't his place to say it.
"I must say she has gotten increasingly better then when she first started" Rossi confessed.
They had all started up the stairs to get a better listen when they noticed you were also singing.
"I want your love and I want your revenge"
"You and me could write a bad romance"
(oh oh oh oh oh)
"I want your love and All your lover's revenge"
"You and me can write a bad romance"
The song turns to a high note and you hit it spot on sending the team into shock.
"Oh oh oh oh oh oh oh oh oh oh oh oh"
"Caught in a bad romance"
"Oh oh oh oh oh oh oh oh oh oh oh oh"
"Caught in a bad romance"
You stop playing in order to take a drink of water. But then proceed to choke on said water when you notice your dads whole team in front of your room. All wearing different expressions. The ladies have similar facial expressions.
Penelope wearing a gigantic smile with her eyes blown wide. JJ with a similar smile just on a smaller scale. Emily's mouth is just wide open and her eyes just as wide as Garcias. The men on the other hand have completely different expressions. Your father looking at you with a proud smile and a certain gleam in his eyes. Hotch is has a smirk on eyes slightly wides with disbelief. Morgan had a smug smile on and was shaking his head in disbelief much like Hotch. What they couldn't believe was how such a small girl had a pair of lungs that powerful. Spencer was completely slack jawed. Because of you both being the youngest, you two were incredibly close. He couldn't believe you didn't tell him this.
You smiled at them awkwardly with a nervous laugh.
"So uhh how much did you guys hear" Derek was the first to speak up, "Oh we heard just enough to know you have a serious pair of lungs and talented hands" he smirked. Rossi cut in, "And long enough to know that probably worked up an appetite"
"Read my mind papa" you smiled
Everyone but Spencer started walking out    
"I wasn't told about this because of..." he had trailed off looking at you expectedly.
"Well it was supposed to be a surprise but I guess cats out of the bag"
He smiled at you "Well it was most definitely a surprise. You did good though super proud that you found a healthy way of coping" Spencer had been the only one that knew of what happened. Your best friend since childhood had committed   suicide. It broke your heart but Spencer was there to comfort you every step of the way. He had dealt with the same thing when Maeve had died. He was super proud that you had found a good coping mechanism instead of throwing your life away.
"Come on let's go eat I am starving and I can smell your dads cooking from here"
You laughed at the statement and shook your head as he wrapped his arm around your shoulder in a side hug as the two of you walked out.
You couldn't have asked for a better family then this one.
