I don't know why I'm getting overly too lazy in posting and seriously at that but if it could somehow help you out my friend, I'll say a few things.
Though it really makes me wonder why nobody even tries to answer your questions... I can only come within two conclusions: 1) The users who are watching this are either dumb, or 2) They hate my gut, my thread, my everything. And if you ask me, it's likely the latter... perhaps due to my monopolizing of the threads in this section. (What can I fuckin do if it just so happens that I love animes so much?!)
Moving on to the matter at hand...
The explosion near the end, on Canaan's side of the coin, is the van that Santana and Hakko was on to while making the most questionable/mysterious(?) surveillance in the series yet.
Yes, they're the most suspicious couple in the series for me right now. I can't tell which side/group they've aligned themselves with nor do I've got any idea on whom they might be working for. From all that I can figure out at this point, it could be possible that they themselves set up that explosion.
Also considering that if you still do remember the details, particularly the remaining masked-person who sought their help, who was in fact being targeted and most probably not only by a single group(SNAKE)... That's why.
The sequence after Santana left the alley where they've parked the van... where only the lower body/leg of several people walking around the area could only be seen... Hakko, moments later, left the alley as well even though he had told her to just wait... And if I do recall correctly, someone else was seen leaving the premises just before the said explosion occurred. - Can you follow where I'm getting at? (I'm really not good in explaining things)
Just ask if there's something in particular, out of what I've said that you didn't quite understand.
Who was killed in the Hotel room of the reporter ?
I don't think anyone was actually killed in that scene as no corpse was practically seen... Or at the very least, no one of that much importance. If I have to make sense out of what the goons did with the blood, it was probably to scare them off or to sniff them out... and as a result, Mino & Maria lost a place to stay for the night.
In any case, don't think too much about it.
Why the hell want this little boy to die ?
And why was this bomb a dummy ? A test for Canaan ?
I bet that kid was working on his own at that time and after what happened to his brother, perhaps he had simply lost the will to live and was practically searching for a place to die, or someone who could kill him. And just to make things a little bit more exciting, he thought of setting it up just like how he did... and I would definitely have to say that it did turn out to be a hell lot of fun.
And can it be that the UA Virus give who is infected a strong curse and a strong blessing ?
Don't you go so suddenly deep on me buddy. :lol: As cliched as that sounds, that's just about it right there.
The people with the "mark" whom you have mentioned are all insignificant characters anyway (except for Hakko), thus I don't give to much crap about them and their abilities. Even so, it was nice of you to point that out and although your English needs some more work, you did well with your comment on Hakko. :lol: (I know what you mean) -But still, ALPHARD FTW! :D
