(Look at my hair, buddy!)

Its not a good look, and Sam has fun at his partners expense.

(Its just who knew you had a chin?)

He should keep those insults coming; humor is the only medicine for this hairstyle.

Kellaher has found several, and he intends to hold Sam accountable for all of them.

Its not personal; its business.

Also, its personal.

Sam dated Kellahers wife, Lillian, just a few months before they were married.

Theres an obvious conflict of interest here.

Isnt there another I.A.

officer who could take over for Kellaher?

We had a dispute as men, he explains.

We settled it like men.

Its no wonder Charmain is the most productive cop in this precinct.

Then theres the matter of Sams favorite informant, who always seems to be where the action is.

This is, impartially, not good.

But Sams job status is the least of his problems right now.

Would taking her call have made a difference?

The last time we see Opal, shes visiting Walt with Sam, whos lost his one bargaining tool.

Opals reply is retroactively devastating: Theres always something.

Kellaher wants a hearing, but Sam is done.

Fire me now or Ill resign, he says.

Its a start, but Sam shouldnt get too comfy; there are no easy wins on this show.

To add to Sams problems, he has to tell Walt that his mom is dead.

Walt wasnt hurt at the protest; he eyes the guard as he shakes his head.

This is prisoner abuse.

Its been one minute.

But Sam suspected foul play, so Shafe keeps digging.

Kimball, who recently married, was still paying for ex-girlfriend Violas apartment in the Bronx.

Viola seems a little bit unhinged.

He stares at his drug supply in the car when he should be going home.

His face is so much more exposed now; it shouldnt be that hard.

Her stodgy recruiter, Captain Perry, asks if shes got a husband or kids.

Husbands dont approve of this sort of work, you understand.

Also,lady parts get in the way of guns.

Perry wants Charmain to infiltrate the Students for a Democratic Society, a group currently protesting the war.

The SDS are a paranoid bunch, and Perrys bosses think a woman might stand a better chance.

This isnt playing dress-up, Perry condescends.

Its a dangerous assignment.

It actually sounds like a terrible assignment.

They snag the key to the penthouse suite and trash the place.

Protesters inconvenience hotel maid, Charmain deadpans later, questioning the larger point of their actions.

One of the guys in SDS agrees they need to think bigger and he has dynamite.

This could escalate quickly.

Meanwhile, Charlie is a jerk.

(News at 11.)

But as theyre leaving, Dennis misinterprets Emmas nervous glances at Charlie and invites the aspiring musician to join.

Classic milk-and-cookie Dennis move.

Either way, shes out of luck.

That night, Emma catches Dennis with another girl, and Charlie has Patty shut her out.

Emma looked touched, so she hasnt dismissed her mom completely yet.

Walk away, Emma.
