i honestly don't know if tosh had fewer lines in this series than Ianto- his were more spread out while she got almost everything in a single episode.

*sigh* Poor Tosh. I'm finding that it's hard to work her into a team vid, because there's so few shots of her, unless it's an episode specifically focused on Tosh like Geeks Bearing Gifts and To The Last Man. Ianto is somehow significant even when he appears for only a minute in an episode -- for instance, he only has two or three brief scenes in Small Worlds, but I keep watching those scenes over and over trying to puzzle out where his relationship with Jack is at that stage. Tosh is just doing background exposition unless the episode is focused on her.
