Cromartie grabs some interesting cheese in Terminator: the Sarah Connor Chronicles episode three, The Mousetrap.
(spoilers)

Out of spoilertv, the following two spoilers have come out:

"Sarah and Derek are put to the test after Cromartie kidnaps Charley's wife; John is in a sticky situation of his own when he finds himself caught between Cameron and Riley."

Since Sarah and Derek must know the kidnapping is a trap, it'll be interesting to see how they handle that. This will give an interesting place to explore the varying ways the characters put a value on life.
