Malcolm wasn't jealous.

No, he wasn't. Not of Reese and that girl he had been talking to for 15 minutes and 32 seconds (Malcolm had counted). It just wasn't possible. Not at all, in fact, that would be weird. The girl really wasn't anything special, you know, she was dumb (perfect for Reese, Malcolm thought, before dismissing it angrily), and kind of bland and furthermore, she had to be lowest of the low if she was WILLINGLY associating with Reese. So there was that. Malcolm wasn't jealous of Reese.

Now, being jealous of the girl, that was what Malcolm couldn't wrap his giant head around.
