Like KrayZ33 said above, I'm really starting to wonder where the "Science crosses Magic" things are actually going to happen in this series. Aside from Touma's Imagine Breaker (which we all assume is science based...), there really hasn't been all that much.

We've had:
- The Tree Diagram getting destroyed by Index.
- All the mages that keep infiltrating Academy City and are promptly ignored by Allister.
- Kuroko getting grabbed by the golem.
- Hyouka (living AIM field) almost getting killed by said golem.
- Mikoto getting stalked by a magician.
- Tsuchimikado.
- Fukiyose getting zapped (is she even an Esper?)

All very minor incidents in the grand scheme of things, and there hasn't been much in the way of anyone recalling any of these incidents as something abnormal. The magicians all know about science and many of the details of it, but the science faction never brings this stuff up ever again.

Tree Diagram is just assumed to be randomly destroyed, though the beam should have been visible on some satellite somewhere. Kuroko should know the golem is not a Esper ability. The only thing it might compare to is one of the AIM field constructs she's seen, but she doesn't even mention that. Mikoto has remembered the stalker incident, but has not yet connected it to anything out of the ordinary, and focuses on Touma's words about her, not what was going on. Fukiyose should know something was wrong with what happened to her, but she seems to have already forgotten it.

The only real cross between the two worlds is Touma and Tsuchimikado. I know the whole point is to avoid a war between the two supernatural factions, but someone from the younger cast on the Science side should have figured out what Touma is up to by now.
