Scribe Counter/Fallout: New Vegas

Scribe Counter is a unarmed perk in Fallout: New Vegas.

Effects
After giving Veronica Santangelo White Glove Society attire or formal wear into her inventory, she will, as thanks, offer to teach you the technique (the outfit may then be removed from her inventory with no negative repercussions).

Use the Scribe Counter to swiftly counterattack opponents. It is performed attacking directly after blocking an attack. The move is quick; with a good enough weapon it will usually cripple the torso of your target.

Bugs

 * Upon giving the formal wear to Veronica, you may get a conversation with her, and have her "teach" you the technique, but upon the screen recovering from being black, you will not have obtained the "Scribe Counter" perk. This bug can be remedied on the PC by using the console command which gives the perk to the player. (Keep in mind that using console commands will disable achievements until you quit and relaunch the game.)
 * This is verified (via reading the scripts in GECK) to happen because of a script bug where a timer object is shared between the "teach Scribe Counter" sequence and the scripts that trigger Veronica's comments leading up to starting I Could Make You Care. If the player gives her the formal wear before triggering any of the nine special comments listed in that quest, the Scribe Counter will be added at the end of the fade-in. Otherwise the conversation, fade-out and fade-in happens, but the perk is not added.
 * You can give Veronica the formal wear, but nothing happens. There is no conversation at all.
 * Several game days after giving Veronica the formal wear she engages you in conversation and gives you the perk.
