On the Same Wavelength

On The Same Wavelength is a quest in the Fallout: New Vegas add-on Old World Blues.

Quick walkthrough
There seems to be a language barrier between Doctor 8 and the player. Certain dialogue options will reveal that a highly perceptive or scientifically inclined Courier can understand the doctor, and use this knowledge as they see fit.

Detailed walkthrough
The player has the task of speaking to each of the Big MT scientists. After exhausting the seemingly senseless conversation options with Doctor 8, the Courier, with either a Perception of 7 or a Science skill of 75, can recognize the scientist's efforts at communication as RobCo termlink protocol and understand him.

With this knowledge, and another Science 75 skill check, the player can choose to exploit this knowledge, or to leave Doctor 8 un-hacked, explaining that they know what it's like to be experimented on (referring to their non-consensual lobotomy). If you threaten Doctor 8, you will be given some (about 30) energy cells and bad Karma. If the latter is chosen, the doctor will be grateful and the player will receive Good Karma.

After passing the check to understand him, the player will have the opportunity to speak with Doctor 8 about the Sonic Emitter, as he is the foremost authority on the weapon, as well as its creator. This can lead to rather humorous dialogue about Doctor 8's seeming fetish over the device, and his method of activating the emitter -- 'sonjaculating'.
