The white cowboy says to the black one, "I like to keep my enemies close". That's one clue. But ignore that for a second and notice how it doesn't make sense for him to say that, given the immediate context - there's an obvious conflict (he just got thrown out a pub) and now he's having a stand-off. The idea of keeping enemies "close" implies that the person isn't aware of who the enemy is. So why would they say that line? Well, that's where Alexa comes in. Keeping unsuspecting "enemies close" through their devices which fill up black ppl homes and spy and monitor their random conversations. lol.
