Gwen gets confused

The dark-haired younger woman who had been standing right next to the woman who had called herself Melody Pond just rolled her eyes and said, "Oh, come on. Not this again. You are not the Doctor's wife."

"What's the matter, Clara?" asked "Melody". "You don't believe in same-sex marriage?"

"Of course I do," said the woman called Clara. "But you're not the Doctor's wife. I've talked to the Doctor's wife and you are obviously not her. So tell her your real name."

"Okay," said the older woman. "It's Professor River Song."

"No, it isn't," said Clara. "Tell her your real real name."

"Okay, it's Idris," said the older woman.

"No," said Clara.

"Donna Noble?" said the older woman.

"No," said Clara.

"Tegan Jovanka?" said the older woman.

"No," said Clara.

"Sarah Jane Smith?" said the older woman.

"No," said Clara.

"Liz Shaw?" said the older woman.

"No," said Clara.

"Romana III, IV and V?" said the older woman.

"No, no, and no," said Clara.

"Jackie Tyle -- No, wait," said the older woman. "There's no way anyone sane is going to mistake a woman of my intelligence for Jackie Tyler. So... Rose Tyler?"

"No," said Clara. "It's Missy."

"Missy what?" asked Gwen, trying to hide her confusion about the conversation she just heard.

"Just Missy," said the older woman. "Though you can call me Mistress. I know Clara often does."

For some strange reason, Clara blushed at this part. Gwen noticed and just shrugged.

Then Gwen asked, "What's your friend's name, Clara?"

"Me," said Clara.

"No, I didn't ask your name," said Gwen. "I asked -- oh, just skip it. By the way, is it my imagination or is it getting a bit cold in here?"

"Well, judging by the state of your bare nipples," said the woman called Missy, "I would say it's not your imagination."

Gwen blushed at the realization that she had so engrossed by the conversation between Missy and Clara that she had momentarily forgotten to cover her breasts. She immediately covered them and whispered a brief prayer of thanks that at least the male members of Team TARDIS weren't present at the moment.

Fortunately, the Doctor said just then, "Yaz. Please take Gwen here to the TARDIS wardrobe room. After all, we don't want the poor girl to catch cold now, do we?"

"We don't?" asked Missy.

But by then, Yaz had taken Gwen by the arm and was leading her to another area of the TARDIS.
