Deadeye, the death of Champions

What is going on???? 1st Zed is dead, then Sona, and Garen will die to some creep called Deadeye which will probably be a Shen rework but Shen is good!!!! Of course he'll kill Zed but Sona and Garen? Something's up. After I saw the death of Sona, I am totally freaked out... ok a little bit. What if Deadeye is an outcast or a rogue against everybody like he holds a grudge on Noxus, Ionia, Demacia, etc. But I am really looking forward seeing or meeting (not in person, obvisously) this Deadeye guy being a new champion in the League of Legends but watching Sona die was creepy. If you haven't checked out the creepy death scene of Sona, go click on the Game info on the top left corner, then click on Champions which would lead you to the Champion info, then scroll down and click on Sona (BTW you'll notice her champion icon is moving).
