Actually, I think adding a new member to the Team in the penultimate episode is a great storytelling device.

Usually, these pre-finale episodes feature a lot of flashbacks and weird "we all should know this already, but let's repeat it anyway as if we just realized it" kind of speeches (like in Revelation). Explaining it to the newbie instead makes the story better.
