As Karyn lead Jon around he was taking some time to observe her. She seemed to really believe she was a guy named Ken. She was walking with heavy steps like a man and her speech patterns were different to how he remembered.
Jon knew it was probably pointless but he kept trying to talk to Karyn. He was growing more and more frustrated when he wasn't getting through to her. Karyn just kept up idle chit chat with him, never once showing any understanding of what he was saying. She lead him into a small bedroom next to her own bedroom. This room was setup for a baby clearly. There was a crib, changing table and some toys on the floor. Jonnfound it all quite boring. It was a lot like his room at home but at least with Biff he could be himself and didn't have to pretend to be a baby. He didn't want to make things too difficult with Karyn so the easiest thing for now was to play his part. He pretended to show interest in the toys, sitting on the floor and playing with them for a few minutes. When he got bored he decided to get up. He had been mimicking the other kids I the daycare so much that it now came natural to him to move like a toddler. To get up off the floor he stuck his butt up in the air and then pushed dupnwith his arms. He wobbled a bit on his feet but quickly found his balance. He turned around to see Karyn watching him with a loving smile on her face. He started to walk towards her when without thinking he stopped and squatted. He couldn't help himself. He crouched down slightly and a grunt escaped his lips as he filled his diaper. He just looked at Karyn, smiled and said, "well Karyn. You wanna be a good dad? Time to prove it. Change my diaper please?" Jon was way beyond feeling any embarrassment for this kind of thing. Karyn picked up her queue. All she had heard when Jon spoke was, "Dada, gooba diapee wease." She seemed up for the challenge and easily scooped Jon up an dlay him down on the changing table. She removed the dirty diaper, trying not to show any sign of disgust and after a few wipes had him dressed in a clean diaper and picked him up off the table. She didn't put him down straight away, instead she carried him around to complete the rest of the apartment tour.
Once in the kitchen, she asked Jon if he was hungry. He replied that he was but the only thing she understood was when he nodded his head. Karyn sat Jon down by the TV and put on a cartoon for him while she cooked some dinner. Biff would allow Jon watch whatever he wanted but for the weekend at least he was resigned to watching kids TV only. Karyn checked on Jon several times while she was cooking. She saw him only as a baby and so was much more nervous about him than Biff was.
A short while later dinner was ready. Karyn scooped Jon up again and strapped him into a baby seat. Biff knew Jon wa soerfectly capable of feeding himself but Karyn was doing things very differently. She sat beside Jon and spoon fed his dinner to him. Jon tried to explain to her that it was unnecessary but she just heard baby babble when he did. Only when Jon had been fed did Karyn eat her own dinner. She was chatting to Jon the whole time, telling him how happy she was to finally be spending time with him. She said things were going to be different from now on. Jon was happy to have his friend back in a weird way but he wished she would stop treating him like a baby.
Karyn saw Jon yawning and remembered the details Biff had sent her. She knew he'd be ready to go to bed soon. She told him the plans for tomorrow. They were going to go for a swim in the morning and the if he was good she was going to take him to a toy store and buy him a present. Jon could barely take in what she was saying. He had become very tired all of a sudden. He found his thumb going into his mouth and felt his thoughts becoming a bit jumbled. He felt safe here with Karyn and just wanted to sleep now. Karyn picked him up and carried him back to his room. It was only when she lay him back onto the changing table after removing his dress that he woke back up a little bit. The table was cold on his bare back and it brought him back to reality. Karyn wanted to change his diaper before bed. He hadn't even noticed but he had soaked it again over dinner. She got him changed and put him into a very soft, very warm onesie. Karyn lay him down in the crib and tucked him in. Within seconds he was fast asleep again.
Karyn crept out of the room and decided to text Biff. She was sure that Biff was worried so wanted to reassure him that everything was going well. Biff was glad to receive the text and asked Karyn to keep updating him over the weekend.
