Lana's boss is very happy with her job performance and really wants her to know it. While he's praising her, she decides that this is the perfect moment to let him know how attracted to hi sexually she is. When he explains that nothing can happen because it wouldn't be professional, she lets him know that while he really needs her, she really "needs" him. After she hints that either he fucks her or she quits, I think we all know what choice he makes.
