Windows is a radar..
Interestingly, in WWII "Window" was the codename the British used for a radar-jamming technique.
It's good to be helpful?
Five targets, presumably that would be... Natalie the illusionist, Kyra, the bluenette who attacked Noah and company, Chernyl D'Aryl and Han Wunchester, the two sprogs they were briefed on who've yet to make an appearance and Malhart himself, the devious painter and sprog collector. The hall monitor with the glasses is another target, but I don't recall him being identified as such.
As an aside, looking back (http://neorice.com/hoh_noah_1213) I do find it a bit odd that the Han boy left a note and scarpered. I mean, Natalie and the glasses brat appear to be attending that school openly, so why not just go on attending as normal? Is it possible he was kidnapped? Team Painter tried to do the same to Noah...
The lack of Ciel is getting disturbing.
Whispers of Sorrow:
It's possible that Han did not join Malhart at all, he went off on his own.
Silly me, the illusionist girl is called Natasha.
@Leo: That's certainly plausible, leaving a note to send anyone chasing him looking in the wrong direction would be a smart idea. Especially if he happened not to like the Painter and company.
