Seb frequently smells as bad as Lex, but different. This is mostly because he staunchly refuses to shower more than three times in a week. If you are ever not sure which twin you are dealing with, breathe deeply. If your senses are kickboxed into an eye-watering stupor by the stinging stench of cheap cologne, it’s Lex. If they curl up and die due to the overwhelmingly hideous moldy pong of sweat, combined with the antiseptic, lemony zing of hand sanitizer, it’s Seb. Easy, see?
