Star Wars Rebels speculation: Darth Vader kills commander Rex !

Hello Star wars fans, I would like to discuss an idea I had for future Rebels episodes.

In season 3 trailer of Rebels we still can see Captain Rex. I really like this character that represents the perfect soldier : courage, discipline, efficiency. He has also a great sense of honor and friendship to both his brothers in arms and the Jedi Generals.

We all know that commander Rex was the officier fighting together with General Skywalker.
They had a great respect and trust for each other and they have made numerous missions hand in hand. They saved the life of each other several times.

To my mind this is part of the reason why he has been used in the Rebels show. He has a connection to Ahsoka (who finds him again) but also to Anakin that is now Darth Vader. Rex talks even shortly of "The Jedi he served" has a great example.

In Season 2, Rex did not met Vader directly and I do not think that Ashoka spoke about who Darth Vader Really is before she disappeared.

I wonder if in Season 3 (or later) we could have a fight between them in which Vader recognizes Rex and eventually makes him understand that his former trusted General is now behind the mask before...killing him.
That would be a great moment full of emotions. Rex would be strongly affected (a bot the Ashoka way) by the fact that his wise and powerful Jedi now became the worst villain. I imagine he would lay down his famous 2 blasters and get crushed by mercyless Vader.

For sure Dave Felloni could make that a very emotional sequence.


Here bellow a very nice video I found that summaries the relation ship between Anakin and Rex. This relationship was created and made so intense by Dave Felloni, I really think that he cannot let that forgotten in Rebels.

Could it happen ? What do you think ?
