Tomorrow, When The War Began - Chapter 8

How does Ellie feel about the lawnmower incident?
Ellie seems to feel like this incident is a burden. She seems to feel like she killed someone and it's not justified.

How does she think the others will react to her story?
She worries that they're going to make a big deal out of it and act as if she is a war hero. Ellie mentions that she 'didn't want to be Rambo, just me: just Ellie.' Luckily no one does react that way, instead they comfort her and Homer even says that the killing is justified.

How do they actually react? Why?
They react with sympathy and comfort her. Kevin, who she thought was going to make the biggest deal out of it, actually just sat there grim-faced. Homer comforts her by stating that the invaders broke the rule book first and how they have no choice.

Homer says, "This is war now, normal rules don't apply.. They're the ones who tore up the rule book, not us" What does this say about his character? What do you think of the validity of his opinions?
Homer has a point to what he's saying. The opposition know what they got into and know that there would've been people who put up a fight. It's also the only way they can play fair. If the group continued following the rules, more then half of them would be dead by now. Breaking the rules to fight a group that have already broken them is the only way to survive.

Fi talks about the 'shadows', during their reconnaissance. What are these shadows? and what are the implications due to their existence? 
I have no idea what the shadows could possibly be but I sort of hope it's something along of aliens. I don't know why and I feel like that might be a little cliche. Even though it's a little cliche and if it was aliens I might be a bit disappointed but I still really like aliens Or even it they were some sort of creature that wasn't Earthly would be cool.

What pieces of information from the book inform the reader that this invasion wasn't entirely peaceful? Find at least 3 examples.
The first sign that this wasn't peaceful is the unusual bush fires described on page 53. There are 6 different bush fires and the reason they're unusual is because, as Ellie describes it, 'It was really too early in the year for major bush fires, but too late for burning off.', this means that something extreme may have potentially happened. Another example is in the story of what Homer and Fi saw when they went further in town. Homer says "Must've been a bit of a battle I think - there were two police cars, bot on their sides, and a truck just down the road that had crashed into a tree.", Homer carries on by mentioning that there were no bodies Fi mentions that there was plenty of blood. The 3rd example is the complete willingness of the guards to shoot at anything that moves. This proves that the guards/soldiers are ruthless and are ready to strike whenever and that this ruthlessness could've caused major violence when taking the town over.
