Alexa's plan to hide her cancer from her classmates and start high school like everyone else is totally doable ... until she starts losing her hair.

The girls come up with a colorful solution to keep Alexa's diagnosis under wraps. But Dave's having trouble adjusting to his daughter's new look.

There's a rumor going around school that someone in the class has cancer. Katie tries out for the basketball team, and Lori starts working from home.

Now that Alexa's secret is out, everyone's being unbearably nice -- even Gwenny. Jennifer and Jack invite themselves over to watch the World Series.

Alexa goes out of her way to prove she can't be punished. Jennifer surprises Jack with a backyard campout but has a hard time getting him to unplug.

After landing the lead in the school play, Katie's left wondering whether she actually earned it. Jennifer asks Lucas to baby-sit.

The doctors order Alexa to stay home, but she can still come to school -- on an iPad. Jennifer works overtime to convince Jack her job is cool.

Katie aims high to win a community theater competition, putting unnecessary pressure on her friends -- and herself. Lucas reexamines his future.

To kiss or not to kiss? Katie's new life as a thespian has Alexa feeling a little left out. Jennifer accuses Lori of stealing her thunder.

Alexa insists on cooking Thanksgiving dinner, but Lori has trouble letting go. Katie's desperate to connect with her dad on a deeper level.

Dave can't wait to show Lucas his alma mater. And with her family away for the weekend, Alexa's ready to break all the rules.

Katie and Ryan don't feel the same way about each other anymore, but neither has the heart to say it. Alexa's determined to pass her driver's test.

Alexa's got such a great support system at the hospital that Katie isn't sure where she stands. Lori pours her anxieties into baking.

Lucas longs for "bro time" now that Dylan and Alexa are hanging out. Dave's nose detects a cat ... and he's not wrong.

Sophomore year is off to a good start for the girls until Katie twists her ankle. That gives Alexa something else to focus on while waiting to hear from her doctor.

Katie is thrilled when chosen to study acting in London. But the $2,000 tuition is way out of her financial range. So she takes on a series of odd jobs trying to come up with the money to send her to the UK.

Alexa gets the doctor's OK to play basketball but struggles on the court. A heart-to-heart with another young cancer patient reminds her of how far she has come.

Alexa's excited to see Dylan again but senses Spencer needs her more. Katie organizes a food drive, and Dave goes overboard on holiday decorating.

Alexa struggles to keep her "real" life -- and her life with Spencer -- separate. A horrified Katie's convinced that her mom is dating Gwenny's dad.

A big fight on the first day of school leaves the girls feeling way out of sync. Lucas starts college, and Lori and Dave toast their 20th anniversary.

Being there for Spencer brings back memories Alexa would rather forget. Katie looks for leadership opportunities, and Jennifer preps for a date.

Alexa takes Katie miniature golfing to get her mind off the SATs. Lori plays matchmaker when Jennifer hires a handsome handyman.

After dating Joe for six months, Jennifer's ready for him to meet her family and friends. It's just dinner ... but Katie's got some concerns.

College acceptance letters are here. But did Alexa and Katie get into the same school? And why are things suddenly so weird between Alexa and Spencer?

Alexa's ready to leave cancer behind her, but it's not that simple. Meanwhile, Katie's trying to balance all the things -- and it's super complicated.
