Technically, while it may have been the end of Lennier's arc, we have no idea what happened between the events in "Objects At Rest" and "Sleeping In Light".
We do know a little even though we haven't seen it as part of the 'documentary'.
In the early drafts of "The Path of Sorrows" and confirmed in the script books, Lennier would have been involved with Lyta's side in the Telepath War and would have been killed in the bombing of the Psi Corps headquarters.

That's a good point. However, I tend to dismiss it because that aspect never made it to film for that particular entry. Consequently, it's not what I'd consider to be a part of the whole story we are told.
