Makes sense.

"While you were sleeping," Tanya said cheerfully and the whole scene replayed in Sam's mind. She saw herself staring at the egg doubtfully, considering all of her options. She remembered thinking about the incredibly attractive woman down the hall and what kind of things she could do... Sam remembered carefully wrapping the thing in a towel and bringing it to Tanya, and a flash of bright light.

"Ok, got it," Sam said. "I'm glad Jake seems to be getting over his guilt. I know old me would have hated this but the worst part of it now is getting his secondhand shame and guilt."

"Oh, we figured something out," Tanya said. "You know how he can make you say stuff and do stuff? He can make you feel stuff too! Why do you think I'm so complacent about all of this?"

Sam remembered how badly she and Jake had freaked out the first time. "So Jake, you can-"

Her words died in her lips as a wave of soporific bliss washed over her. As she flopped back onto the couch, she noticed Tanya sagging back against the wall. Tanya made a funny noise, a kind of "wahmfs" sound, and Sam giggled. Tanya giggled too, which made Sam laugh even harder. Soon they were in stitches, Tanya bent over and clutching her stomach while Sam pressed her face into a pillow.

Suddenly their laughter stopped and they both stood straight. Tanya's red, tear-streaked face was now completely stony. "Point taken," Sam said. "So now you're making us serious?"

"That's right," Tanya said. "Jake and I have been doing more experiments. He can really do some wild stuff! Watch this."

She left the room and came back with a guitar, which she handed to Sam. "I don't know- oh, ok," Sam said and sat down with the instrument. Her left fingers hesitatingly formed a chord and she strummed. Then another, and another, then she was playing some kind of repetitive riff while she gawked at her hands.

"I'm playing guitar!" she said with awe. "I don't know how to play guitar!" There were a lot of missed notes and awkward transitions, but she realized (probably from Jake) that it was because she didn't have the muscle memory. She finished the riff with a loud strum on a Cmaj7 chord. She had no idea what that meant, but she also knew that it was a standard C chord with a high B note added.

She put down the guitar, not sure whether it was because she wanted to or Jake wanted her to. "You've been busy," she said. "I'm impressed. Any other tricks you two want to show me?"
