All right, I take a break from homework to bring you more reader questions and their answers!

Are there 3 people running around in that universe looking like Selena Gomez? She plays Alex on Wizards, Mikayla on Hannah Montana, and she guess starred on one episode of Suite Life as a girl named Gwen, Cody's love interest.

I assume so. Now a case could be made that to the people in the universe itself, they all look different. Remember that no one thought Maddie looked like Ashley Tisdale (although that was a joke), but more importantly, no one seems to have said "Say, Miley Stewart looks a lot like Hannah Montana." Denial is a wonderful thing, so they deny that they look alike, because that's impossible. Actually, the only story I have submitted is centered around Alex looking like Mikayla.

Why do people on the SWAC universe know that Miley and Hannah are the same people (except for Chad Dylan Cooper)? Are they in the same mind set as us or did Miley/Hannah blow her secret there?

I think Sonny takes place in what is essentially our universe – well, one that is a lot closer anyway. After all, Selena Gomez is an actress in the SWAC universe. So to them, Hannah Montana is just a TV show (and a media sensation, but not a secret).

Does this mean that SWAC can NEVER have a cross-over with Wizards, Suite Life, or Hannah Montana?

I find it unlikely, especially because Selena Gomez appeared there and because of the comment that Chad Dylan Cooper thought Hannah and Miley were two different people. Especially the latter, actually. If it had just been the Selena thing, which we could make a case for because Ashley Tisdale was actually referenced by Maddie, then I'd say there could be four people who look like Selena in that universe. Alas, the Miley/Hannah thing clinches it – it's in another universe.

Why don't they ever mention Hannah Montana or Mikayla on Wizards? They mention Tears of Blood (TOB), some random MCR spoof band Justin likes, but not one of the most popular singers in that universe? I can sorta understand not mentioning Mikayla, but not Hannah Montana? She gets dozens of awards and is insanely popular in that universe, and not even mentioned in passing...Seems like a singer at least Harper would like.

You want the real reason or the in-universe reason? The real reason is that mentioning them would distract from the plot. As writers, you should never put in anything that does that and, ideally, everything should further the plot. When writing comedy the rule relaxes to "Should further the plot or be funny." In-universe though, I'd say that Alex and Justin don't like Hannah, and Harper refrains from mentioning her out of politeness.

In the episode "Saving Wiztech", Dean was put in a huge block of jello (or something like that), the gang went to Wiztech for AT LEAST a week, and then Dean was freed from the jello a day or 2 later. Wouldn't Dean, or someone who knows Dean, realize how long he's been gone? I mean really, someone's gotta notice his random disappearance!

Dean is portrayed as the kind of kid who might disappear for a while anyway, so I imagine that no one really noticed. On the other hand, he would notice something. Fortunately there is a memory erasing spell, which can really act as a deus ex machina for a lot of things. Another possibility is denial, again. There is something magical that makes mortals not want to believe in magic, so they dismiss a lot of things as coincidence that we would find absurd. (In "Movies", there was the line about "How much did you get on that deductive reasoning test?" Even someone who got a 99 on that will deny magic as a possible cause of anything!)

Not to mention, how do Justin, Alex, and Max all get excused to leave school and go to Wiztech in the first place? Because in this Wiztech episode they made it clear that this wasn't during the summer, unlike the first.

Parental excuses can get you out of a lot.

In the movie, why did Max and Justin remember what happened after Alex reversed the spell and not Jerry and Theresa?

For that matter, why did Alex? She wished everything back the way it was, after all. Anyway, I assume it's for essentially the same reason they didn't disappear right away, either. Magic is lazy.

Why is it that in the movie, Max appeared to be more grown up than in the TV series? He seems more serious and mature about magic and other things.

He also seemed more capable. I guess he's just maturing, actually. We might see a more mature Max in season three, actually.

We all now know that Dean moved away and that's why he wasn't on the show. Why didn't they mention it in earlier episodes then, instead of leaving us wondering where he went to all this time?

This show has a few problems with continuity, it's true, but also, it must not have really come up before then. At least not until they needed a plot around it.

In the show, several times, the Russos mention magic, or even use magic in a public area, for example, Alex talks about magic in the hallway with TJ in the episode Art Teacher. How can they not be exposed like that? Also, in the episode Art Teacher, Mr. Laritate comes out after Alex's conversation with TJ and says that he overheard what she said, but yet didn't reference anything to magic. How can that be?

When they're in halls they are supposed to be whispering, but they don't really because of convenience to the audience. It's sort of like having an aside in a play. The thing with Mr. Laritate is odd, of course, but see, this also ties back to the whole idea that mortals deny magic as a possible cause. He's so conditioned against it that he either didn't hear it or didn't understand it, completely psychologically.

In the episode, Tutor Tutor, Max gets a tutor for magic. But why doesn't Alex, since she clearly needs a tutor the most, as shown by the backfiring of her spells?

Actually, her spells usually go pretty well, it's just that she doesn't always make the best choices with how to use spells. Max, on the other hand, seems to have trouble even casting spells.

If you can travel trough time, even for a few hours why not write down the winning lottery numbers or something like that and return to your time to win it, you could even give it to a mortal friend so it would never be known.

My theory is that traveling in time inherently alters the timeline, so that if you travel forward to get lottery numbers, you'll change what those numbers are. Then they won't do you any good, because they'll be different when they're selected "again", when you travel back in time. Of course, this opens up the "what about time travel paradox" can of worms, but I always liked to believe that those kind of ironed themselves out. Like, there's a way the universe is supposed to be, so the space-time continuum constantly flexes back into that position.
