I'm waiting very patiently for Ianto's relationship with lisa to fall apart... (hint, hint) Ianto himself may be determined to make it work, but I'm not so sure that's what Lisa wants.

Jack's a tonic for Ianto though, lifting his spirits with good company and conversation, and Martha can see Jack's interested, even if she's dismissed the thought now that she knows Ianto has a girlfriend. Well, who knows what tomorrow will bring?
