So all this time we have Anna and Marcus building up how special Tyler is and how essential he is to their plan, then two episodes ago he leaves and Anna says no big deal because they've got other options, then this last episode Tyler is important again and just like that comes back to them. Does that about sum it up?
Check out this line from the comcast tv guide description of next week's episode:
"Tyler may be useless to Anna"
And around we go...
Just like he's useless to the rest of the universe?
