Several hours after the funeral, Izzie finally returned to the house. Many hours of thinking had resulted in her being no farther along than she had been earlier in the day. Dropping into a stool at the breakfast bar, Izzie stared blankly at the wall. Meredith drifted, bleary eyed, into the kitchen and opened the fridge.

"You okay, Iz?" she asked, taking the stool next to Izzie.

Izzie shook her head in response. There wasn't really an easy answer. "I have a lot on my mind."

"You've been crying," Meredith stated.

"So have you," retorted Izzie.

"I'm sorry…"

After a brief pause, Izzie sighed, "Me too." She slipped out of her seat and trudged towards the stairs. Her legs were suddenly shaky, and she suddenly found herself sitting on the floor.

Meredith rushed to her side. "Izzie, what's wrong?"

Izzie's eyes welled up. "I don't feel well," she whispered.

"Oh, Iz, you are way too stressed out. You seriously need to get some rest."

"It's not that," Izzie answered, so quietly that Meredith could barely hear her.

"What is it?"

"I don't want to talk about it," Izzie said hurriedly, reaching out for an end table to pull herself to her feet. She pulled herself up on the table, but her legs still wouldn't support her, and she fell back to the floor, taking the lamp with her.

Meredith reached down and put Izzie's arm around her shoulders, hoisting her friend up gently and helping her to the couch. "Let me make you some tea, okay? Get something in your stomach?"

Izzie nodded mutely.

When Meredith returned to the living room, Izzie was curled up in a ball on the couch around the box of Kleenex. Placing a mug in Izzie's hands, Meredith said, "Spill your guts. Seriously. 'Cause I'm not helping you upstairs until you do."

"I…feel…very guilty," Izzie muttered.

"Iz, you can't feel guilty for what happened to Callie. You had no control over it, you had nothing to do with her accident...You did the…"

"The best I could?" Izzie finished. "But…it's not even about that."

"What is it then?"

"I really don't want to talk about it. Seriously." Izzie took a sip of tea and set her mug on the table.

"Izzie, you have…"

"God, Meredith!" Izzie interrupted, exploding. "I slept with George! Are you happy now?"

Meredith opened and closed her mouth, no words coming out.

"I slept…with George…" Izzie repeated, tears streaming down her face. "I slept with George…and that's why he and Callie aren't…weren't…together anymore…He was distracted, he failed his intern exam…because of me…and Callie wanted a divorce…and…"

"Izzie, I…I didn't know." Meredith wanted to reach out a hand to her friend, but she wasn't sure how to help. "I…"

"You didn't know because no one knew. And you probably would have been the first one I would have told, but…God, I don't know what to do, Meredith. George won't even talk to me, and there's…so…There's so much that I need to say, you know?"

"I know," Meredith affirmed.

"Part of me thinks that if Callie were still here…it would be easier…but the other part…" Izzie broke into hysterical sobs, leaning into Meredith as Meredith wrapped her arms around her.

"Make what easier, sweetie?"

Izzie mumbled an answer into Meredith's chest between sobs, but it was impossible to understand.

"What? I couldn't hear you."

Izzie lifted her head up, looking at her best friend and struggling to keep breathing. "I'm…pregnant, Meredith. I'm pregnant."
