When Edwin and Lizzie let their siblings out they expected to be either bombarded with queries as to how they got stuck in there or a tidal wave of fury as Casey and Derek had worked out that they had shut them in there.
Therefore it came as a big surprise when the pair ignored them and simply bolted for the bathroom and then proceeded to have a fight to get in it first.
Once refreshed, Derek and Casey practically ran to the kitchen for food. While there they discussed their plan.
"How do we get the handcuffs on them? I mean, without them knowing. It's practically impossible." Casey said as she poured them both drinks.
"But it isn't completely impossible. We can do this. We just need to think." Derek said, buttering lots of slices of bread for them.
Casey paused as she pulled various sandwich toppings from out of the fridge. "I have an idea." She said pensively.
Derek gave her an encouraging look as he relieved her arms of some cheeses.
"They won't notice it if they're asleep. But they don't sleep in the same bed. Now, I happen to know that Lizzie tends to get scared at night and usually when she gets scared she crawls in bed with me for comfort. She won't do that now because she's scared of our reaction. So, naturally she'll crawl into mum's bed. We have to get our parents out of the house. If mum's not here then she will have no choice than to go to Edwin for comfort. One of us hides in Edwin's room and handcuffs them when they both fall asleep again."
"If we can pull that off then we'd win the Nobel. It's a good plan though, and so far the only one we have. Well done, Case!" he said giving her a quick kiss on the cheek as she handed him the marmite.
Nora and George entered the room with Marti in tow.
"So I see you finally got out of the room. I will have words with Edwin and Lizzie at some point." George said smirking.
"There won't be any need for that. We've found a way to get back at them." Derek replied calmly.
"You're not going to do anything too terrible to them are you? I know they can be a pain in the neck sometimes but we would prefer it if you didn't kill them. Think of the mess that you'll be cleaning up if you did."
"Oh no, nothing like that. We're taking a leaf out of their books and owning it. I assume that their plan was to make us loathe each other again, well believe me when I say that they will loathe each other by the time we get through with them." Casey said winking at Derek.
"All we ask is that you leave us alone in the house for an evening with them. Will you do that?" Derek said taking her hint.
"How long are we talking?"
"Until they get to sleep. Or try to."
"When do you want us out?"
"I think we should have a few days of showing them that we are thoroughly annoyed with them and to set up our payback. Is that okay?" Casey asked taking a bite out of her sandwich.
"What did Ed and Lizzie do? Were they bad?" Marti asked innocently, sauntering over to stand beside Casey. Casey lifted her onto the counter and offered her some of her sandwich.
"Yes they were bad. They locked me in Smerek's bedroom with Smerek himself. That was very bad of them wasn't it? They left us in there for a whole day. Do you want to help us?"
Marti nodded and Casey smiled at her.
"Then whatever you do you mustn't give us away to them. If you want to you can ask one of them to play with you while the other is doing something important."
"I don't understand."
"You will, Smartie, in time."
