The trouble with secrets is that they have a habit of revealing themselves at the most inopportune moment. And although the news of Siavash and Noirin's kiss isn't general knowledge yet, it can be only a matter of time until Marcus finds out and hell breaks loose.

"What are you doing?" giggled Noirin from beneath her quilt as Siavash stood over her.

"Standing here with my hand in my pants," replied Siavash as he played pocket billiards. "Why?"

Then Noirin's voice suddenly dropped to a whisper. "Who's in here?" she asked

"I am," replied Siavash quietly.

"I've got a pumping headache – did you spike my drink last night?" laughed Noirin.

"You took advantage," Siavash said to her.

"I took advantage?" gasped Noirin, adding "that's what I do!"

And then conversation turned to a certain long-haired male housemate. "Marcus doesn't seem very…" Siavash began.

"I had to tell him to get out of the bed. He was lying next to me and I told him I didn't think it was a good idea to lie next to me," interrupted Noirin.

"It's a difficult, difficult situation," sighed Siavash.

"Just be cool," replied Noirin.

"I could not talk to him today. I woke up and he was there and I could not say good morning," said Siavash guiltily

"You haven't done anything wrong," protested Noirin, before considering the situation. "I was thinking you're going to have to say something," she added.

"What do you say?" Siavash asked, before suggesting that Noirin should take care of that side of things.

"You're so kind," replied Noirin sarcastically.

Big Brother wouldn't want to be in your shoes Noirin…
