 This is the statement I responded to.
 It was YOU who introduced Stella's view ("for Stella").
You even called it "the key to the paradox" and "the brilliant explanation".
If Stella shall return to Terrence, she _must_ accelerate during
her journey, so Stella's frame is always an accelerated frame of reference (in flat spacetime).
 But it isn't beautiful, even if it true.
 Stella's view is rather pointless.
 As I said:
Nothing happens to Terrence clock, it runs normally.
It is _only_ Stella's idea of what is simultaneous that
make it appear that Terrence clock run fast.
 If you change Stella's path in Terrence frame a little,
Stella's view of Terrence may change it a lot, because
Stella's idea of what is simultaneous changes.
(You can change the path without changing Stella's and Terrence's proper times.)
 If we describes the "twin paradox" in Terrence's inertial frame,
Stella's view adds nothing of interest.
 So we can do without Stella's view of Terrence.
It is certainly not "the key to the paradox".
 

 t'es vraiment con comme un balai : tu as foutu toute ta "réponse" en ... signature.
 you are stupid as stone: you put your entire "answer" in ... your signature.
 Trump is inspiring you, I'd say :-)
