He's an interesting character that -we've seen so far- really defines himself by those around him. In 'Fragments' we're shown three differing personalities that Ianto dons in order to try to get Jack's attention and we can see that the prim Butler we were introduced to in 1x01 is perhaps not the REAL Ianto Jones at all but a character he's been playing for Jack's benefit (as well as his own). He did that all for Lisa then when she's gone he begins to live for the job and Jack which grew into the relationship they got now.
I realize I'm rambling a bit now but one last thing~ People were thinking he was off in Sleeper with his humor and somewhat 'up' behavior (which many said was due to some good sex :D). But its possible that in season 2 we're finally getting to see him be comfortable and be himself.
