A/N: I'm on fire today! I already got two out and this is my third! Well, it's one for the Mentalist, which is a first for me, but I love the show, and I think I can do it. So we'll see. Please enjoy it for what it is, being my first.

Lady Madonna, a Mentalist fic

"Arrest him! He assaulted me!" Jane screamed, pointing from Lisbon to the suspect, holding his nose.

"Jane, you hit him first!" Lisbon was tired of playing mom to the arguing school-boy, especially when both these men were fathers themselves. It was disturbing to know how slowly some men matured.

"It doesn't matter, you can assault him for arresting an officer! I mean-" Lisbon cut him off, knowing what he meant and not wanting to hear it again

"Sir, I am going to have to take you into the station. You did assault an officer. You can also be taken in on an obstruction of justice count if you don't give us the information we need."

"Okay, fine!" The suspect grumbled, climbing into the cruiser.

"Jane, was that really necessary? The man already hated you enough to try to break his nose, and you had to torment him in the interrogation room for half an hour while he was hand-cuffed? Ten minutes, I can see, but 30? Good god." Lisbon lectured steadily, only taking a breath when Jane ventured up the courage to speak.

"Yes, mother!"

"Shut up! I don't know your mother but I pity her, having to deal with you for years!"

Jane's mouth snapped shut, and he took on a somber, slightly hurt expression.

"Don't talk about the things you don't know, Lisbon." His playful tone was strained, his smile was forced, and he walked away quickly, leaving Theresa feeling guilty and petty.

"Really? Am I really buying you mint-ting-a-ling ice cream because I hurt your feelings? God, I feel like a mom. You're older than I am! This should NOT be happening-" Her words were cut off by Jane playfully shoving her ice cream into her mouth. She'd ordered the same thing as he, and it didn't go unnoticed. (Nothing ever did.)

"Eat your ice cream, Theresa." Jane was enjoying his, practically inhaling it.

"Jeez, did you taste any of that?" Lisbon asked skeptically when he had finished a few seconds later.

"Yes, and it was delicious. Now finish yours while I order another."

She shook her head and smiled when he wasn't looking. Maybe he was one of those guys that was never going to fully grow up. She'd make a great mom, and she knew it. Little boys were her specialty.

A/N: I know, it's just a short little thing I came up with.. I loved it though. Maybe it wasn't perfect, but I thought it was cute. Lisbon loves being the mom-like figure to Jane, even if she constantly complains about it. It's such a great show :D
