Teen Mom 2 kicked off Season 5 with a shocker:

Jenelle went through with an abortion. Having gotten knocked up by Courtland - without a home, without a job, without custody of son Jace - the young mother didn't think it would be fair to anyone to bring another life into the world.

And Babs actually agreed with her daughter for a change, driving her to the clinic and paying for the procedure.

Yes, these two still got into a fight afterward. But it was an unusual, raw, emotional experience for MTV to actually depict on air.

As for the other young ladies?

Kailyn wants to be close to Javi, but Jo is legally challenging her move.
Leah received heartbreaking medical news about one child.
Chelsea has a new reason to worry about how much time Adam will spend with Aubree.
