New Champion Unknown SR Teaser

Well, last night while i was playing a ranked game of rengar. I first noticed this little purple pinkish line shoot out from the wall of the bush at me, with the enemy team having a jinx at first i thought it was zap, but it wasn't.Later i then see it right before dragon dies a little purple line over him shoots out same as last one. Next at blue buff same thing I kill blue buff and purple line shoots out of wall. I'm positive this is the new champion teaser where we recently had that video, it makes sense this is happening in the jungle. I tried to get a picture of it in the game but couldn't will keep trying to get a picture of it. If anyone see's it get a picture or record it i too will continue to try and capture this Thing that i think is a teaser.
