Mind you I still think it took lazy by surprise, she said yes it is because to me it sounded like she also thought he said brother then realised he said forever, still think there is a secret brother somewhere..
I was thinking along the same lines.
Earlier on, Jace said that he hoped that the microphone didn't need batteries. Judging by his facial expression, he said it in such a way that implied that he'd been disappointed by battery-operated toys in the past.....maybe because they didn't have the right batteries and he couldn't use them straight away, or the batteries ran out quickly...something like that.
So later on, in the clip in question, I think he asks about the batteries lasting
forever.
I can see why people are hearing "brother" though and I also reckon that's what
Lazy thought he'd said,
initially. Then she twigged that he was actually talking about the batteries, so she backtracked and responded accordingly.
Somehow I can't see the (alleged) secret son sending random gifts for his half-sibling. As others have said, it's possible that there are ifam kids who have been described as being like brothers to him and he's possibly latched onto that.
If Lazy
does have another son on the way though, and that's why she unwittingly thought Jace had mentioned a brother and she just naturally went along with it, without thinking, then she's just outed herself. That would be hilarious.
