What happened in 7x16: "This isn't my dream."

"You didn't think it was...that impressive," Callie observed.

"Sure," Arizona replied sarcastically. "He handled it. And not like a four-year-old." She sighed, looking up at Callie curtly before returning to fake-reading the newspaper in front of her. "Is that supposed to make me excited?"

Callie was dumbfounded. "I thought I was supposed to be the cranky, hormonal one."

Arizona finally made eye contact with her girlfriend. So, she was being a little passive aggressive. She knew that. But, could Callie seriously blame her? "I'm not cranky," she insisted.

"Mm," Callie hummed doubtfully.

"I don't get excited about Mark. I'm not delighted by Mark. I love you. And I can honestly say that I'm gonna love this baby."

Callie smiled.

"But Mark? I somehow ended up agreeing to a lifetime with," she shrugged unhappily, "...Mark. A lifetime of decisions: bottle or sippy cup, basketball or tap, Dartmouth...Berkeley."

Callie's eyes pleaded with the blonde, but Arizona wouldn't look at her girlfriend.

"Christmas morning. With...Mark."

Callie leaned back, exasperated. "Okay." She couldn't deal with this tonight.

"I never picked him. And I don't hate him, but I don't want a life with him. And, yet, somehow that's...what I got." Arizona smiled sadly.

"What am I supposed to do?" Callie asked. She felt lost. "Kick him out? I mean, it's his kid."

"Yeah," Arizona agreed, appearing to refocus on the newspaper at hand but not actually reading anything. "You don't need to remind me of that. I never, ever forget that."

"Wow," Callie rolled her eyes. "Okay. We're going to go down that road again."

Again, Arizona folded up the newspaper. "Okay, can we just be honest about the fact that this is some kind of 'bi dream come true'? I mean, you get the woman that you love, and the guy best friend who's also a great lay, and then you get a baby. I mean, you get it all," she laughed darkly. "And me? It's...this is not my dream. My dream, doesn't look like this." She turned back to her newspaper. She didn't have the energy to get into this anymore. This was just her new reality. She had to accept it. She knew she had to accept it. It was just hard.

Her body language made it clear that she didn't want to talk about this anymore, but Callie felt like she couldn't just leave things like this. She was tired, but she knew she wouldn't be able to fall asleep knowing that Arizona was having such a tough time.

"Arizona..." Callie breathed pleadingly. "Can we please talk about this?"

Arizona turned the page of the newspaper. "Nothin' left to say."

Callie ducked her head a little to try to catch the blonde's eye. Arizona ignored her.

Callie: "Would you please look at me?"

Arizona sighed, then finally turned her head to meet Callie's eyes.

"I'm sorry that you don't like it that Mark's in this now. That he's our family. And I'm sorry that it's the constant reminder that I had sex with him. But, Arizona..."

The blonde sighed. The truth was that nothing Callie said would make her feel any better.

Callie forged on, despite Arizona's sardonic expression, "You have to understand that the only reason I had sex with Mark was because I missed you."

Arizona's eyes widened.

"You left me heartbroken in the middle of the airport, and you didn't ever call. I waited for you. I didn't get out of bed for three days. I was so sad...and lonely."

Arizona let out an empathetic breath, finally shifting on the couch to move toward Callie, placing a reassuring hand on her thigh. Callie eagerly grabbed it with her own and intertwined their fingers.

"I didn't do it because I like Mark or am attracted to him. I'm not. I just missed you. I was drunk, and I missed you, and he was there."

Arizona gave the slightest of nods, feeling a little better. Mark at least wasn't a romantic threat. He was just a friend. Family. He'd be in their lives forever, but Arizona would be the only one of them who was With Callie for the rest of their lives.

"Okay?" Callie asked pleadingly, desperate to lift Arizona's mood.

Arizona offered a slight smile. "Okay," she whispered.

"And, hey," Callie began, trying to lighten the mood, "Think about how much money we'll save on childcare. When we want to get away to a beach to drink sangrias, we can just leave the baby at Mark's."

Arizona smiled almost genuinely. "You in a bikini?" She recalled.

"Of course," Callie grinned, "As soon as I lose the stupid baby weight. I feel so fat already."

Arizona leaned in and left a tender kiss on the brunette's lips. "More of you to love," she insisted.

Callie let out a wavering breath, thankful for having successfully assuaged Arizona's insecurities. Just a little.

"Seriously. You're hot," Arizona vowed.

Callie blushed, beaming.

"How about," Arizona husked into her ear, "I show you just how hot I find you."

"Mmm," Callie acknowledged flirtatiously, raising her eyebrows.

"Come on," Arizona stood up, pulling Callie up with her and leading them toward their bedroom. She knew that she still wasn't completely okay with the whole Mark situation, but for tonight, she was willing to let it go. She had a beautiful girlfriend, and she would have a beautiful baby.

And for tonight, that was enough.
