LOS ANGELES — Kaitlin Olson is back to show us more of her “High Potential” for the show’s second season.

She loves her character, Morgan – a genius single mom who has found her groove professionally by sharing her genius IQ to help police.

The cast returns for a new round of mysteries at the precinct.

“I aim to keep you guessing. Our goal is to lead you to believe one scenario and then perhaps completely surprise you,” Olson explained. “What I appreciate is that these characters are multifaceted. You can expect a mix of everything.”

One thing this cast shares: chemistry.

“We have such amazing people who are incredible actors but who are also just wonderful human beings who are excited to be here,” Olson said.

Olson particularly loves when Morgan’s brain is on fire and she’s starting to solve a case.

“I love acting without words. I love listening, I love having my eyes do their own thing,” she said. “That’s the part that I really like.”

Another highlight: Morgan’s colorful way with her wardrobe. And Olson is happy that part of the character will not be changing.

“You will not be disappointed. You might just be even more delighted this year,” Olson said.

“High Potential” airs Tuesdays at 10 p.m. ET/PT, 9 p.m. Central, on ABC.
