Picard Did the Right Thing! (PATRON TAKES S3E7&8)

I love the cave background. Have you noticed an abundance of cave episodes in both TOS and TNG?

Already previous plots get in the way of some good medical tension, instead of blood transfusions PIcard could just ask Tomalak for the transporter trace and beam a healthy crew member back to the Warbird.

Assuming that Worf gave his consent or if Picard forced him to submit to the procedure, it would not have gone further than that since the Romulan refused to give his approval and without patient consent, this operation would not have happened. So, unless they could have persuaded the Romulan (which was highly unlikely) then the outcome would have remained the same.
