Jeff decided to find one of his sisters, and hide in their clothes. They'll mistake him for a bug! And if they ever end up looking, he can simply hide somewhere else.
So now Jeff had to locate them. He runs out of his room, under the door since he can't open it, and now he realizes; If they're downstairs, he may not be able to get to them. "I'll have to deal with that problem when I get there...". Jeff starts off though by checking his sister Megan's room, seeing she's not in there. He then checks the bathroom; nobody in there either. "Dammit, I guess they're downstairs. Alright, how do I get down safely..."
Jeff weighs his options; He could try going through the wall, although he doesn't know if there's an opening downstairs from it. He could try the stairs themselves, though he'd probably hurt himself from jumping down each step. That's when he thought of it; "I could slide down the railing! Perfect idea."
Jeff decided to try that option. However, he needed a way up onto it... "Hmmm... could I climb up it like a pole? I'll try it...". Jeff then goes over to one of the poles, and attempts to climb it; Surprisingly gaining traction against it to climb.
================ Time skip; 3 minutes later ================
It took him a while, but Jeff finally got on top of the railing. "That took too long... now to get down there". Jeff goes over to the edge, where the railing starts to go down. He could walk down it, but he decides to take the fun way; Sliding down. So, Jeff sits on the railing, and then pushes himself down... and immediately regrets it. The metallic railing burned his cheeks as he slid down; And once he reached the bottom, he went penis-first into the finial. "FUCKING OW!"
After recovering from that... incident, he slides down the pole, and carefully gets off the last step. Once at the bottom, now he gets to search the house for his target. First checking the downstairs bathroom, once again nobody is in there. He then goes to the living room, nobody there. That's when he sees someone in the kitchen. He runs over there, and sees that both of his sisters are here. "Alright, now where do I pick..."
