It’s your basic “boy-meets-girl, boy-becomes-cryptid” story, really. A woman walks into a laboratory, and the chemistry experiment begins.
As we’ve discussed, the three steps to getting the audience to like a character is to make a friend, make a joke and make a plot point, and Dr. Alec Holland is about to do all three in record time. The appeal of Swamp Thing is half superhero-action and half romantic drama, so it’s only going to be effective if it can get us to believe in Cable and Alec as a couple, during the limited amount of time before he explodes.
So this meet-cute needs to be practically automatic, establishing that both parties are smart, funny and attractive, and getting them to challenge each other in sparky mini-clashes that are interesting to watch. The time-honored method is to get the characters to stick their hands in a murky water trough, looking for an imaginary animal.
