It would've been better if something had gone wrong with the Caretaker pulling them to the Delta Quadrant, and they never made to the Array and were dumped in some other part of the DQ. So they never met him, they never knew what brought them there, etc.
maybe Ransom pissed of the Caretaker and the Caretaker thought: "Screw them, I will say I have not enough energy left to send them back"
