(Beware, spoilers below!)
This episode of The Big Bang Theory Leonard has to give a commencement speech at his old high school. However, his flight gets cancelled and him and Penny trudge back home. Howard helps Sheldon fix a drone and Raj gets bad news when his dad cuts off his allowance. The next day Penny buys Leonard a cap and gown because she convinced his high school to let him give his commencement speech via Skype.
Meanwhile Howard has taken apart the helicopter drone, which sends Raj into a panic because he needs to get the money back. However all is solved when he he wheedles his mother into being given more money. Howard tries to fix the the drone, but it goes wrong and he ends up calling tech support. Raj’s dad calls up and Raj manages to wheedle his dad into giving him more money.
Leonard gives a commencement speech but realises that what he’s saying is actually quite boring, a gives a speech to address all the kids like him that might have hated high school or felt invisible. Afterwards him and Penny go over to Sheldon’s – but the drone has been taken over by someone else and is wreaking havoc.
This episode was a mixed bag that allowed the power players of Sheldon and Howard to step back and allow Raj and Leonard time to shine on their own (which is great considering their storyline last week). Leonard displayed how his bad experiences has made into not just a successful, but also a more profound person while in contrast Raj doesn’t seem to have changed at all. He might have mature with people, but he’s still a papa and mama’s boy. On the back burner it gave more interaction with Howard and Sheldon that built on last week. Though their actions were fairly inconsequential, it allowed for the two to play off one another in a manner of cooperation that – of course – allowed for some great physical comedy.
