 This relationship develops further in Series 2 with Jack asking Ianto out on a date ("Kiss Kiss, Bang Bang"), the pair sharing an intense kiss ("To the Last Man") and Gwen walking in on them during some kind of sexual activity ("Adrift").The other characters also allude to their relationship; most specifically Owen ("A Day in the Death") and Gwen ("Something Borrowed") and ("From Out of the Rain").While Ianto becomes comfortable hinting on things going on while in bed with Jack around the other team members, he is uncomfortable to do so out of the Hub as shows.
