John 13:27

But instead of moving Judas to compunction μετὰ τὸ ψωμίον, τότε εἰσῆλθεν εἰς ἐκεῖνον ὁ Σατανᾶς. μετὰ “after,” not “with,” “non cum offula,” Bengel and Cyril, who also says, οὐ γὰρ ἔτι σύμβουλον ἔχει τὸν σατανᾶν, ἀλλʼ ὅλης ἤδη τῆς καρδίας δεσπότην. On ἐκεῖνον Bengel also has: “Jam remote notat Judam”. Morally he is already far removed from that company. But what was it that thus finally determined Judas? Perhaps the very revulsion of feeling caused by taking the sop from Jesus: perhaps the accompanying words, Ὃ ποιεῖς, ποίησον τάχιον, “what thou doest, do quickly”. τάχιον : “to Attic writers θάσσων (θάττων) was the only comparative, and τάχιστος the only superlative”. Rutherford, New Phryn., p. 150. The idea in the comparative is “with augmented speed,” see Donaldson's Greek Gram., p. 390.
