Sooo.... Gankplank And Sion most likely encountered Kindred before

First of all, the little teaser is in the Ability preview of the champion, where Lamb attacks both Gankplank and Sion.

From what we can see (to say this like Lamb would): "Where Kindred goes, Death is sure to follow". They looks like avatars of death or something like that.

So i's pretty clear that both Sion and Gankplank "SHOULD BE DEAD". This basically tells us that they saw Lamb and Wolf already, or at least they dreamed of them.

There are 2 special quotes that Lamb tell to both Sion and Gankplank:

TO Sion: Let us end this mockery To Gankplank: We meet again (Dont remember the exact words but that is the essence of what they say)

Soooo... Lore nerds tell me what you think, what can we expct from now on from these 3?
