I don't know if the videos got shuffled, but I'm seeing it on this one at about the time you listed:

While watching this live streaming yesterday, my take on it was not RHornsby's - I was
not sitting on the edge of my seat waiting for Lee to talk about molestation. My mind wasn't even in that ballpark. JA was objecting to JB asking the same question over and over (I thought JB was doing it just to reinforce the poor family dynamic, denial, etc), and Lee was just emoting his sense of betrayal at his family shutting him out. I wasn't detecting any potential bombshell coming. Just a man crying over some bad family resentment and feelings of isolation. When Lee finally said, "No, no other reason" my sense at the time was that he was pretty much implying, "Isn't that reason ENOUGH to be upset?"
Only after watching it again today after listening to legal analysts opine that JB and Lee had reached an agreement that Lee would say he was angry because he thought it was George's baby, and Lee backed out at the last minute - watching the video this morning I can see that JB looked angry that Lee said there was no other reason, and I can see that in sidebar he probably told HHJP that the reason this testimony should be allowed in over objection was because Lee would be talking about molestation.
I can't imagine that HHJP would have listened to JB's argument at sidebar that Lee be allowed to ask "why ELSE were you angry?" - and HHJP himself cautioned Lee that he was supposed to answer "besides the reasons you've already stated" if the anticipated answer was "No other reason". So clearly there was the JB expectation that Lee would bombshell us and he didn't.
But to my uninformed mind watching it unfold in real time (like the jurors) I was just taking it for what it seemed. Lee upset over feeling left out with some legal wrangling in the background over semantics. Wasn't expecting a bombshell at all.
eta: and I can see NOW especially after Lee is still sniffing into the mic after the non-bombshell, JB walks over to CM who is looking like "I can't believe this" and CM gives him the "what can you do? let it go" gesture and JB mumbles "no further questions" all defeated and small.
