Leah
Really can't believe how much she rushed into things with Jeremy. Living together after 2 months, engaged and then pregnant (not sure about how long a time space). I feel sorry for him as well because he seems like a nice guy and it's so obvious she doesn't know whether she wants to be with him or Corey. He must feel so uneasy. Really want to bash her and Corey's heads together and tell them to talk about everything because it's obvious they are both contemplating trying again, but waiting for the other to admit it. (and yes I do understand it was probably filmed like two years ago and she has married and had a baby with Jeremy since).
Chelsea
I'm so glad she passed her GED

I do like Chelsea, I think she is just a typical girl who keeps falling for her ex even though it is such a bad idea. I think she needs to get out there and move on, she can do better than Adam. Her 'baby' voice does annoy me though.
Kailyn
I never realised how much she wanted to be with Joe, it seems like she thought they were going to get back together until he got with Vee. Didn't understand how she was allowed Isaac around Javi (what seemed straight away) when Joe wasn't allowed Vee around him, also thought she dismissed Vee's letter very rudely. I quite like Kailyn but find her annoying at the same time..
Jenelle
Actually seems like she has improved slightly since coming of drugs etc! I wish she would do more with Jace and actually act like his mother - I know she doesn't have custody but still. I hate seeing her walk out on him.
