But later on, her personality suddenly changes.

She drops the hippie persona and focuses much more on her education and her impressiveacademic accomplishments.

Maybe her personality changes because, over the years, she grows up and the character’s interests shift.

The change is drastic, but it fortunately fits well with the show’s pace in later seasons.

That’s when Nicksay was replaced with a different child actress,Lindsay Ridgeway.

But Ridgeway brings a much different feel to the role of Morgan.

Ridgeway brings some maturity to the role.

Still, it’s jarring to see Morgan suddenly look different in Season 3.

But it’s not common that a role goes through quite as many actors as Topanga’s parents did.

Where’d she go?

And odds are most viewers didn’t even notice.

For one, he doesn’t treat Topanga very well.

It would be a sweet moment… if Cory and Shawn didn’t respond with laughter.

Congratulations, you’ve killed my spirit."

Thecast ofBoy Meets Worldis pretty incredible.

That probably went over kids' heads, but it was still pretty suggestive.

While these jokes were pretty funny, they might not have been so appropriate for young viewers.

It’s clear that they’re talking about having sex for the first time with their girlfriends.

This is demonstrated in the scene when Topanga tells Coryshe loves him.

This focus on relationships gives the show a certain depth and maturity.

But the show explores lessons beyond relationships like irresponsible drinking.

Cory and Shawn are caught drinking after Cory steals alcohol from the liquor cabinet.

They end upurinating on a police carandget arrested.

“So, how’s it feel to put one over on your parents?”

Cory’s dad, Alan, asks.

“You feel good?”

Cory responds with a timid, “No.”

It’s clear his drinking caused him embarrassment and shame.
