TWENTY-EIGHT, DAUGHTER OF A MINISTER, COLLEGE GRADUATE, ELECTRONICS ENGINEER, SINGLE NOW AFTER A BRIEF MARRIAGE.
She is the daughter of a minister, so we can assume that she will side with Mr. Blake because he sympathizes with anti-Catholic views. Some may argue that this may cause some (additional) feuds with Father Frans, due to the fact that he is Catholic. This may be true, but since they are working towards basic necessities at the moment, Father Frans can be excluded from the same jobs that Mrs. Clark will take part in. Both Mrs. Clark and Mr. Blake have experience with mechanics and engineering, so they can work together for the shelter and building aspect of their survival. Also, she will be able to reproduce with the males on the island. This is key if they want to have more people grow to be able to help out on the island, assuming that they will be stuck there for many years. Plus, the group will get old and eventually die of natural causes (if they haven't died before) so they need to continue the population.
