[2020] You can see Ekko and Warwick in Sumpsnipe Scavenger's artwork

Here's the full artwork, look in the top left (zoomed in here). Notable since Sumpsnipe Scavenger (aka Ajuna Lem) is tied heavily into Ekko's lore, as in the Chronobreak comic (link to Surrender at 20 bc the Universe link is broken for me) we see Ekko try and fail to save Ajuna's life and in the Seconds cinematic we see Ajuna's broken goggles. Also Ajuna's mural breaking at the end of the cinematic leads to the final rewind (if you haven't watched Seconds do so now, it's the best cinematic Riot has made imo).

Since the new Riot show seems to be focusing on Vi and Jinx and the Zaun kids in general, and Warwick appears to also be in the show (?), this is a fun shoutout, although I think the show takes place well before even the "time" of LoR as Jinx and Vi are still kids. From dialogue from LoL Ekko knew Jinx and Vi when they were still in the gang, so it's possible he's also in the show, but Ajuna looks significantly younger than even Ekko so I'd doubt he'll be in the show. Still fun though!

Now if only Scavenger was playable.
