Not a nit as such... but wouldn't replacing a warp core be something that you would go into spacedock for? It's a pretty major bit of equipment, after all. If it doesn't work, the ship is stranded years away from anywhere unless somebody comes and tows them back home.
Also, why does Data go and consult a holodeck character about his dream? After all, there is a real live counsellor on board - one whose knowledge of psychology isn't four or five centuries out of date, at that. Shouldn't he go talk to Troi herself?
Data starts having really strange dreams. Has he finally reached his use-by date, or is something odd going on?
