On the Teen Mom OG episode ‘Mother’s Day’, while Amber spends the day with her family on the lake, Catelynn is at home with her husband Tyler and daughter Nova. When Tyler’s mother Kim stops by for a visit, she asks Catelynn about her stay at a rehab facility where she was treated for depression. “So it was helpful? Did you learn anything?” Kim asks Catelynn who laughs and replies, “I learned a lot of crap.” Kim doesn’t laugh. She tells Catelynn: “I could’ve sworn you were high the other day. You’ve been smoking pot, haven’t you?”
Catelynn says it’s not something she wants to talk about, “I don’t want the whole world to know.” Kim is surprised. She turns to her son who says he’s keeping his mouth shut. “I have to keep my mouth shut because she’s responsible for her and I’m responsible for me.” Catelynn agrees and says “yeah.” Teen Mom OG airs Mondays at 9pm on MTV.
