So comparing this to the scene let’s be real we all know TROS was inspired by, look how much time eclipses between the >“we’ve lost” moment to the “everybody’s here!”. There’s this tension that’s slowly building as the heroes gather >together. It’d be so jarring otherwise (as we see in TROS).
https://youtu.be/xp2YlHPAyVI?t=62I was so sure you were gonna link to RotJ! Besides, Endgame wouldn’t have been out when the script for RoS was finalized. The cavalry arriving to the rescue is just a classic trope.
It’s even in Trevorrow’s script.
In fairness, Trevorrow’s script had that being an actual mission the heroes were on. Not vague dialogue with a cameo character who comes back as a deus ex machina, especially one that’s so telegraphed but not earned.
Trevorrow had it being the main characters actually contacting these people and bringing them in. It was part of the main plot and mission.
