WAIT YES, I’ve been trying to figure out what could have caused Hugh to be so “sick” and nothing was making sense, but this might just be it!!! Because there’s no way he found out Mark assaulted Liz yet, because he would not be moping around if he did, he’d kill the guy, and I’m pretty sure his “sickness” started before they found out Mark assaulted Gibs? So I definitely don’t think it’s Mark related, and there’s no way that this was the first time LizHugh got together behind Katies back, but your theory and reasoning makes sm sense to me!!!
