Tyler's dad Butch adjusted to life outside of prison during this Teen Mom OG season and endured some unforgettable experiences during those initial months of freedom -- holding his granddaughter Novalee for that first time, witnessing his son say "I do" and contemplating his living arrangements, to name just a few.
And while the MTV grandfather was not given permission to travel to the Los Angeles-based reunion because of the conditions of his parole, he did join Catelynn, Tyler and host Dr. Drew via video chat to reflect on this past installment -- and one specific scene: meeting Carly.
"It's my granddaughter, she's got my blood in there," the Michigan native reveals in the sneak peek above from Monday's episode. "She's beautiful; she's gorgeous. I was walking through the corridor -- it wasn't planned."
But when the "Butch Breaks It Down" frontman saw the six-year-old, he could not resist approaching her and shaking her hand -- which was not well received by her parents Brandon and Teresa. How did the couple's reaction make Butch feel? Play the video to find out -- plus, watch Butch get emotional talking about Tyler in the video below. And be sure to catch Part 2 of the Teen Mom OG reunion on Monday at 10/9c.
