I would agree that they are definitely not on good terms. It appears that JL has a restraining order against him and he is not allowed to see Baby G.
From the
PPH article:
"A protection-from-abuse order forbids Linnell from seeing his daughter, according to court records."
So it isn't just the D's that have anger issues. I know everyone is quick to jump all over the D boys but playing Devil's Advocate here, none of us really know what was said to them by JL nor why LD chose to assault him. I am sure there is more to the story than 'You've been saying stuff about my family. Knock it off,'... Just my .02
To throw an outrageous theory out there (there certainly have been a lot mentioned already), perhaps JL broke in to steal his own baby & she wasn't in the room (sleeping with her mom that night) and took Ayla instead. As in, you can have your baby back when I get mine back... Outrageous, I know, but a possiblity nonetheless.
