Yeah, I got the impression the story Jade told the MC happened a while ago, and maybe nothing actually happened (Jade never confronted Burke nor Cathy to find out if anything did happen or just if Burke was thinking about her - similar to how he's always thinking about Bella in the scenes we see). But I feel like the discussion in the bar was regarding something new. Like Burke seeing her Swyper account and using it to his advantage somehow (luring her somewhere under false pretenses).
ca "I need another drink."
ja "Do you really?"
ca "Why are you so mad with me?"
ja "I'm not mad with you. I was upset, but I'm over it."
ca "I didn't know before going there."
ja "I know and it doesn't matter. None of that matters now."
ca "You hate me."
ja "I love you. And I'll support you, even though this is the worst thing that has happened in a very long time."
ca "You're my best friend."
ja "And you're mine."
ja "Maybe you shouldn't drink more."
mc "(I shouldn't interrupt, but...)"
mc "(Fuck... I thought she'd stay strong.)"
That line, "I didn't know before going there." That stuck out for me.
And the last line from the MC, classic misdirection to make us think it's just about the Cathy Cluck.
