Sherman and Polly came back from school…

Sherman

"School Sweet School…

It's so good to be back on our time after some adventure in the wayback…"

Polly

"Yeah…sure…

Sherman…

I must tell you something…"

Polly was about to tell the truth when some police cars arrive…

She was taken to custody while Mr Peabody explained that his friend kidnapped Christine…

Many hours later, Sherman was so blue…

He was sure "Penny" was innocent…

Meanwhile, the real Penny showed up …

Penny

"Hi Sherman…"

Sherman

"Penny! I thought you'll never come!

Hey… Where's Mr Peabody?"

Penny

"He'll be history once I'm done with you…"

Penny was about to kidnap Sherman but Polly arrives just in time as the two sisters fight…

Sherman

"Two Pennys ?"

Penny

"No ! I'm the real Penny! Your friend!"

Sherman

"No! I'm your friend Sherman!"

Sherman

"You're right… You're the real Penny…but you're not my friend!"

Penny

"What ?"

Polly made a karate move to Penny to knock her down…

Sherman saw the bitemark at Penny's arm as there was nothing in Polly's…

Sometimes later,

Christine and Mr Peabody was freed by the police who arrest Penny and take her into a juvenile delinquent school…

Sherman keeps contact with Polly as she came back to her original school…

Mr Peabody's adopted son and Penny's twin hangs out every week end, like they did after their journey in the WABAC

THE END
