I think the only onscreen evidence we have for 'Ianto taking Jack out somewhere' is the weevil hunting in Fragments, isn't it? Other than that, the relationship has mainly played out through encounters presumably in the Hub (handjobs in Adrift, the hockey stick in the Hub, etc.) So while I think this entry is a tad more understated than what was posted for Fragments, it's still annoying that it's the blog that keeps referencing these 'dates' (using 'date' here as shorthand for 'Jack and Ianto doing things as a couple that don't involve sex in the Hub).
