Get/got

[Xinfu]

p.593

-"Despicable," Mr. Crouch spat at Dumbledore, sitting down as Bagman walked out of the dungeon. "Rookwood get him a job indeed....

Why get not got?

[Rusty]

Mr. Crouch is simply repeating here what was attested just moments before by Bagman.
To wit:
"And Rookwood kept talking about getting me a job ..."

I would have said, "Rookwood getting him a job indeed," to exactly match the verb that was used.

Thank you for the answer, but I'm still confused; why would Rowling think get was correct?

[Rusty]

I didn't say that get was wrong. There is nothing wrong with the sentence as it is written. If I were reflecting on a previous comment, I would have used the same verb form the original speaker used.

Thank you; could you think of another example of this kind? (using the bare infinitive)

Anytime you are critical of or disbelieve what you have just heard, you can repeat a part of the phrase that you want to deride.

Here is a quote from The Wizard of Oz that illustrates this. I've highlighted two statements made by the wicked witch and the corresponding expressions of derision.

Dorothy: You know, we were just wondering why you couldn't come with us to the Emerald City to ask the wizard for a heart.
Tin Man: But suppose the wizard wouldn't give me one once we got there?
Dorothy: Oh, but he will. He must. We've come such a long way already.
[the Wicked Witch appears on the rooftop of the Woodsman's cabin and cackles loudly]
Wicked Witch: You call that long?! Why, you've just begun! Helping the little lady along are you, my fine gentlemen? Well, stay away from her, [pointing to the Scarecrow] or I'll stuff a mattress with you! [toward the Tin Man] And you - I'll use you for a beehive. Here Scarecrow, want to play ball? [she hurls a ball of fire at the Scarecrow, who draws back in terror from the flames burning on the ground near him]
[The Tin Man quickly beats out the flames, as the witch disappears]
Scarecrow: I'm not afraid of her. I'll see you get safely to the Wizard now whether I get a brain or not. Stuff a mattress with me, eh? [tries to snap his fingers defiantly, but his gloved fingers produce no sound]
Tin Man: I'll see you reach the Wizard, whether I get a heart or not. Beehive! Bah! Let her try and make a beehive out of me! [snaps his fingers, making a harsh "clank" sound]

Note that the Tin Man could have sneered "Use me for a beehive! Bah!" instead of the shortened form.
Had the witch said "I'll make a beehive out of you," he could have said the last phrase I highlighted.

Thank you; I will need to ponder over it for some time.
