Lisbon, She's the one ! No just kidding

Seriously what's up with these people ?
To whom died and were supposed to be their friend ...
Why Lisbon and the team aren't showing any kind of mourning.
Or even showing some interest about what's going on.
They are all psychopaths.
First, Ray Haffner, then Ardilles, now Laroche.

We can't come up with any real theory now, this is just nonsense.

Why do we still hope for a future explanation xD
