Is the sentence in blue correct grammatically? Do you think that it should be "go on par with that"? Because we should use "do" after "make", am I correct?
This is from an American TV program,
Karl: Oh. So you were jealous?
Susan: No! No! It's just... we were married. And...and she's trying to make this tawdry little affair you guys have going on par with that. It's just... I got mad.
The 'on' could belong to either "going on" or "on a par".
What's going on here?
We're having an affair.
They are having an affair going on, or they have an affair going.
She's trying to make this tawdry little affair you guys have going on on a par with that.
By the way, are you sure that's from an American TV program? I only ask because Karl and Susan are a couple (surname Kennedy) in "Neighbours", and those two lines sound entirely as if they could be from a storyline which involved them. "Neighbours" is Australian.
