Stephen Dillane and Clémence Poésy’s character relationship is discussed in what can only be described as a superficial way. The strand notes there is no sexual tension, but rather a brother-and-sister liaison. With Elise falling in love for the first time on other shores, so to speak, the fact that this particular interaction in the series is without depth and not believable isn’t addressed – she’s the nearest thing Planet Earth has to a Vulcan, hence why her sort-of ‘falling in love’ just doesn’t gel.
