Tough times: The impact of Ryan Edwards' troubles on his family is illustrated in Monday's edition of Teen Mom OG, as his parents Jen and Larry Edwards learn about his July 23 arrest in connection with a parole violation

'You don't know if there's gonna be a trigger,' Jen said, while Larry added, 'In addiction, you just never know - you never know if today's the day.'

The father-of-two sons - infant Jagger with wife Mackenzie Standifer, and Bentley, nine, with ex Maci Bookout - is currently in a rehab facility following a stint in rehab last year, and not expected to leave the facility until next year, a source toldUS Weekly earlier this month.

Bentley took news of his dad's absence particularly hard, Larry said.

'He asked me out there in the garage [where Ryan was] ... I knew he knew, but I knew he needed to hear it from us and I told him the truth,' Larry said. 'I told him, "The most important thing is that your daddy's clean." And he started crying.

Sad: Larry explained how he broke the bad news to grandson Bentley over his dad Ryan's rehab

The concerned grandpa said that Bentley gave him a 'big hug' and he did his best to reassure him that things would work out.

'I said, "Buddy, he's going to be OK - he's got us, and he's going to be fine,"' said Larry, who noted they were concerned for Standifer as well.

Bentley's mom Bookout told her Teen Mom peer Kailyn Lowry that she was less stressed about Edwards when he was in custody as opposed to on the streets, for his own sake.

'I feel better that he is in jail because I know he's safe there, if that makes sense,' she said in an August appearance on Lowry's Coffee Convos podcast. He's not doing something that could potentially hurt him or an innocent person. So it sucks, crappy situation for everyone.'

Teen Mom OG can be seen Mondays at 9/8c on MTV.
