1) It has been less than a month since the battle at the Yeerk Pool where Tobias lost his humanity. This entire book resolves around Tobias dealing with being a hawk and a boy. How do you think he's been handling it?
Better then I would be. Like sure, he tries to kill himself a couple times, but I mean, who wouldn't? Not only is he stuck as a hawk, but the hawk mind is starting to take over and replace his human mind.
2) Kind of going off of #1, how do you think the idea of Tobias hunting for food is handled? What about the girl hawk and his suicide attempt? Realistic?
The girl hawk I felt was a bit meh, although it is kind of important for an emotional tug on the heartstrings at the end. The rest of what you mentioned, IMO, is as realistic as you can get with a human stuck as a bird.
3) When Rachel and the others are in the belly of the transport ship they are convinced that they're going to die. Tobias says, <Rachel, I never told you....> and Rachel answers with <You didn't have to, Tobias. I knew. Good-bye> what do you think Tobias was going to say? That he loves her? Keep in mind they've only really known one another for a month or so...
Not that he loves her, but probably that he has feelings for her, at the very least. Even before they officially met, he's probably seen her around the school and may be in some of her classes.
4) Marco is so opposed to being an Animorph at this point in the series. Why do you think he keeps agreeing to come along?
Because those are all his friends, and he wouldn't be able to live with himself if he knew they died and he could have done something to help. Plus he knows the fate of the entire world is in the balance, so even though he doesn't want to do all this, he knows he has to, cause there's no one else.
5) Rachel has a picture of Tobias in her drawer. Any speculation as to how she got it since she didn't know Tobias very well just a month ago?
Could have been from before Tobias got stuck in his morph, but after they got their powers. Could be she was crushing on him before they ever actually met (See my above answer for Tobias' feelings for her), and she somehow obtained a picture of him for her to oogle over in private, like so many girls do.
6) Anything else?
Not off the top of my head, but I'm sure stuff will come up through discussions.
