Well,i have an idea. Zed's video is about his eyes and he is completelly about shadows ( lack of light/sight ). Sona's video is about her throat and mouth and she is completelly about sound.

i know zed doesn't kill ppl with his eyes and sona can't talk (at least in normal manners) but i believe, teasers focus on something they lack ( zed can't be seen and sona can't be heared) but use as a weapon (zed kills with shadows and sona kills with music) .I believe, teasers can be about a new champion who uses others abilities aganist them in some way. But it is way too early to be sure about anything.
