 In "Cyberwoman" the pair share a kiss, although it is essentially a kiss of life, it is not done in the normal way, and resembles a kiss of lust rather than of life.At the end of "They Keep Killing Suzie", Ianto subtly presents Jack with a sexual proposition, which the latter appears only to understand after a few seconds - he accepts by telling Ianto to meet him in his office in ten minutes, once the rest of the team have left the Hub.This is again alluded to in the "Instant Messenger Transcript" provided on the official website, which represents a conversation between the pair in the time remaining before their tryst.
