The obvious flaw in 'Alison's plan... What flaw?

Just then, Peter noticed the obvious flaw in 'Alison's plan.

"Dad, you don't sound like Alison. At all!" he remarked.
"Oh son, that is easy to fix!" the mentioned told, picked up the iBod and changed some settings on it.

"Now I should sound just like Alison as well!" she said in Alison's perfect soprano.

"But Dad, how is that possible? Didn't you explain to me recently that in order to transform yourself, you need to fire the iBod at yourself?".

"Yes and no, son! See, the iBod engulfs me with a forcefield which moves my original body into a subspace pocket while projecting a hard-light hologram in my original position. This means I can tweak the parameters of my new appearance somewhat and... Well, let me show you!".

Next, 'Alison' pressed another button on the small device. And instantly, Peter saw how her body seemed to expand outwards, fattening her up tremendously in the process.

"See, I can alter the hologram's weight and put a lot of flesh to my bones! Or I can go even further and alter my age!" she mumbled as she pressed another button.

Now Peter got the shock of his live as he saw how 'Alison' got older, loosing some weight in the process.

"Damn Dad... You seem to have thought of everything! But could you please revert back to the original Alison's appearance?" Peter echoed.
"Of course, Peter! But maybe you should start calling me Alison, I am not your father anymore!" 'Alison' said and pressed another button.
Seconds later she was back to normal.

"So, Peter... Got any activities for the day yet?".

"Well Da-er, Aliso... Not exactly! What you wanna do though?" Peter asked.

Now 'Alison' beamed at him.
