The fact it’s hard to know if Villanelle actually came during the hookup, which she completely dominates for her own pleasure, points out a flaw in how viewers have been trained to view sex scenes. Women “need” to make a Sebastian-like big show of their orgasm because that’s the only way to know they even achieved one — after all, it’s always entirely possible they won’t. Men, however, don’t have to make such a big display because it’s always expected they’ll finish. If sex finishes on a TV show, it’s usually because the man did as well. Considering what we know about Villanelle — she’s the jackhammer in all situations, sexual ones included — she probably wouldn’t allow Sebastian to wrap things up in the bedroom if she wasn’t already taken care of. Just because she doesn’t show as much doesn’t mean it didn’t happen.
