The episode opens on Montana teaching a “midnight aerobics” class when The Night Stalker (Zach Villa) randomly walks in. Montana completely ignores the fact that he appears in pain and says, “Hey, Rambo, my class isn’t for poseurs. This is aerobics…it’s serious.”
After class, Montana heads into the locker room only to find the dead body of a boy she had argued with just a few minutes ago.
“You like my surprise?” The Night Stalker says as he approaches her from behind.
“That’s the most f***ed up thing anyone has ever done for me,” Montana responds.
Right on cue, Montana drops a bombshell and asks The Night Stalker if he’s a murderer, because she has another job for him. You see, her brother—Sam—was killed while serving as a best man in Brooke’s wedding. (We first learned about this information back in episode two, though we didn’t know Montana’s relation to the victim.)
So, she wants Brooke to pay for her brother’s death. “I know Brooke f***ed my brother,” Montana says. “And now he’s dead.”
