While Pete spilling his feelings to Beth may have been a little too on-the-nose dialogue-wise, Kartheiser was still strong. In fact, Pete was responsible for many highlights this season including several fistfights, his night with a prostitute and the Pete-centric "Signal 30," which was an early season standout diving headfirst into his psyche (drip, drip). With all the death imagery hanging around this season, many had pegged Pete to finally put that office shotgun to use and off himself but he appears safe for now -- that fate fell, unfortunately, to poor Lane.
After a failed attempt to commit the act in his new Jaguar, he stages a second try at work, and this time he doesn't miss. The partners find Lane the following morning hanging in his office accompanied by a boiler-plate resignation letter. Though many viewers may have sided with Don for doing every decent thing to conceal Lane's misdeeds and save him the humiliation (not to mention jail time), Lane obviously felt he had still been wronged and left his own body as a giant “fuck you” to Don. Harris agreed, telling Vulture, “It was a vindictive thing to do, to kill himself in the office, so without question he went back in there and wanted to be passive aggressive — the act of killing himself in the office is the aggressive part and the passive side of it is to leave a suicide note that explains nothing.”
Betty Francis (January Jones) once again received fairly minimal screentime this year, and though some may place the blame on Jones' real life pregnancy, most viewers know that Betty hasn't figured heavily into the show since she left Don in Season 3. She probably received about as much screentime this season as she did in Season 4. Though her weight gain proved an interesting development for her character, its execution was lacking, and the only real misstep of the season was the Betty-centric second episode "The Tea Leaves" (though it did spawn the brilliant parody "Fat Betty" for which we are all grateful). As the season wore on she did get some great notes to play. Betty catching the sight of young, thin Megan changing in her room was a crushing moment for her character. Throughout the season, fans experienced emotional whiplash feeling sympathy for her one moment and being reminded why she can be so unlikable the next. (And repeat.)
