Yeah for sure. Closed captioning during Ezra's walk through the Lothal Jedi temple actually even reveals who was saying each thing & what they were saying... so that's really cool. It's nothing new, but cool to know who's saying what.
Wookieepedia sayz this about Jacen
Jacen was a name shared by:
1st one's out cause he wouldn't be old enough & Corbit worked for the Empire.
Jacen Qe-Kora or Jacen Unimar could possibly be Jacen Syndulla... maybe he changed his name to remain anonymous or something. Not sure which Battlefront game those Jacen's were in... but the last game "Renegade Squadron" happens "many years after the battle of Endor..." Not sure exactly when, but 4 or 5 year old Jacen could be a player as early as a pre-teen. Ezra was only 14 when he joined the crew of the ghost. This is a bit of a stretch, but might be possible.
Jacen Solo is a stretch... but might just be a shout out to the EU character.
Jacen Yar was a bounty hunter during the pre-quil era. (rise of the empire era)
Lol at the last one. Allana Solo named it Jacen so she could talk to it when pops wasn't around.
