Tonight is the finale of Teen Mom 2, and just a heads up—you will cry. A lot. The entire episode is emotional as we see the girls' stories come to an end, but this clip, of Leah and Corey taking Ali to a doctor's appointment, is especially a tear-jerker.
Watch the EXCLUSIVE clip above to see how Ali's first of many tests went down and what the doctor said about her condition and if she'll ever walk. Also, how cute was Ali's phone call with her "sissy" back home?
And don't forget, the hour-and-a-half long finale of Teen Mom 2 is on tonight at 10pm on MTV! How do you hope all the girls' stories end? Did you get choked up watching this clip? Tweet us @OKMagazine and leave a comment on our Teen Mom Facebook page.
