Leah Calvert It's baaaaaaaaack! Teen Mom 2 returned to MTV tonight for its fifth season, and it's like the drama never left. Jenelle Evans had an abortion! Chelsea Houska's ex acted like a jerk! And Leah Calvert and Kailyn Lowry had some pretty heavy moments in there too.

In fact, despite all the sturm and drang over Jenelle's abortion in the run-up to the big premiere, I dare say the goings on in Leah's life ended up taking the front seat.

That's because Leah finally let the audience in on her family's biggest and most devastating secret -- what is "wrong" with daughter Ali.

It turns out one of Leah's two twins has a rare form of muscular dystrophy. The condition has many forms, and some sufferers will grow up with little effect. Aliannah, unfortunately, has a congenital muscular dystrophy that is more severe. It was present at birth, and it's degenerative, meaning although she's currently toddling along with sister Aleeah, she will eventually be confined to a wheelchair. The disorder also affects Ali's respiratory system and that too will progress the older she gets.

"It felt like someone kicked me right in the freakin' throat," the Teen Mom said of getting the final diagnosis. I'll fess up -- I had actual tears in my eyes when Leah came out with the story in a one-on-one chat with pal Kayla.

Controversies and drama aside, we've watched these kids grow up right in front of our eyes. It's hard NOT to get emotional about something this big.

But then, if I'm being really honest, the big diagnosis wasn't the only moment that got me teary-eyed.

Kailyn had her baby shower tonight, and oh my God, if you didn't cry when Javi got up and started waxing poetic about how much he already loves Isaac, you are a MONSTER!

Kail may have had a rough start to life with a crappy mom and then the troubles of being a teen parent, but everything seems to be going so much better for her these days. Granted, Jo is giving her trouble about moving with Isaac, but Javi is a definite keeper!

If only Chelsea could find a guy like him!

More From The Stir: Kailyn Lowry Wants to Be a Role Model for Crunchy Moms

The South Dakota mom is single (and proud of it), but her ex has suddenly decided to show an interest in little Aubree after all these years ... or at least an interest in taking Chels to court. Does Adam really think he's going to convince the American public that he's Daddy of the Year just because he's got a second girl pregnant?

And then, of course, there was Jenelle. We saw the abortion. Or rather, we saw her trip with son Jace and mom Barbara to get the chemical abortion and heard her explaining what was going on. Opting to take pills rather than go in for a surgical procedure, the much talked about decision wasn't nearly as dramatic as one might have expected.

Frankly, I was glad. MTV handled a very touchy subject with respect, which is exactly what women need. And let's face it -- there will be plenty of Jenelle drama to come later this season.

What did you think of the way MTV handled the abortion issue? Were you surprised Leah finally shared Ali's diagnosis?
