Tidbit: in Matalas’ intentions he wanted to reveal she was beamed out at the last moment and held captive by the changelings.m but they had no budget to film this (and a lot of other stuff). All in all I think it’s better this way: she went out in a blaze of glory and this kind of “nobody ever dies” philosophy is kinda the opposite excess of what they did in season 1.
I didn't know that, about Matalas' intention for Ro's final scene.
In this instance, I say thank goodness for budgetary constraints. It seems fortuitous that Ro got the ending she got rather than what was originally intended by Matalas, if that was indeed what was intended.
The last time we saw Ro, in TNG "Preemptive Strike", she was also on board a shuttle. It was fitting back then, that Ro's last act in "Preemptive Strike" was her beaming out of the shuttle, in order to join her Maquis compatriots.
Her beaming off the shuttle was a fitting symbol of her abandonment and betrayal of Starfleet and of Picard.
This time around, in "Imposters", Ro stayed on board the shuttle and demonstrated her loyalty to Starfleet by making the ultimate sacrifice by crashing the shuttle, in order to defend Starfleet.
Those two contrasting shuttle scenes were the perfect bookends to Ro's character arc.
The questioning of Ro's loyalty and trustworthiness was a recurring theme in Ro's arc. In "Imposters" Ro's character arc had come full circle, once again.
