a couple episodes back Ahsoka Tano mentioned she was looking for Grand Admiral Thrawn
I don't know if you have ever watched the animated series Rebels , but the main character on that show is a young Jedi named Ezra Bridger
and at the series final episode both Grand Admiral Thrawn and Ezra Bridger disappear into the outer rim
Ahsoka Tano is really looking for both of them , so if Grand Admiral Thrawn returns ,( which would be pretty frickin cool by it's self ) most likely so will Ezra Bridger , and the cool thing is , Ezra Bridger would pretty much the exact same age as Luke , maybe a year or two older
seeing Luke Skywalker and Ezra Bridger together , would be pretty awesome
another year ,
