They decide to do that

The three sisters headed to the attic to consut with the Evil Book of shadows on how to cross into another world.

"We can use the portal in magic school but if there magic school is as active as ours we wouldn't get far" said Phoebe.

"Want they just think we're their Charmed Ones." asked Paige.

"Yeah we cross an interdimensional portal and we come from their world, try using something other than your pussy to think for once." snapped Piper.

"Not a problem all me need is a dark secluded location, now shortage of alley ways here no reson to think there aren't any there." said Phoebe scribling down a spell.

"Good I'll tell Chris and Leo to watch the boys." said Piper.

Moments later Paige orbed the sisters into an alley way accross town where Phoebe quickly proceeded to draw a mystical symbol on the ground and then a door way on the wall in chalke before reciting a spell.

As they did a bright light burst out of the chalke line and a rippling effect appeared between the lines.

"Our doorway." said Phoebe stepping towards it.

Emerging on the other side the evil sisters were greeted with the sounds of heavy traffic and people moving about their day to day lives.

"Ugh it's so bright and cheerful." shuddered Phoebe suddenly disturbed by by Piper laughing, "what is it?"

"it's you." said Piper pointing at a nearby bench with Phoebe's good phoebe's image on it.

"Oh god I'm a crappy advice coulmist." said Phoebe.

Piper continued to laugh.

"Hey just imagine what kind of joint you run, or maybe your the stay at home mom now."

"Your right, I could be some sad pathetic housewive or the owner of some classy resteraunt or bar and i bet over here you actually have a job."

Paige made a disgusted look.

What do the Evil Charmed Ones do where do they go first, what season have they arrived in 7 or 8 what are their evil plans.
