Considering how much time Marina spends on dry land, why was she so adamant against doing a short overland drive through Scotland? It would have made more sense to suggest that she, a marine creature, would not be able to tolerate fresh water. At least this gave Atlanta a chance for some more screen time, although why did they imply that they HAD to have a third person present? Or was Troy just being thoughtful?

Just fire off a torpedo at what seems to be an extremely rare living creature? Tut, tut.
