Playing The Walking Dead game on iPhone, how am I able to get Carley back for Episode 2?

I saved Carley instead of Doug back in Episode 1, but now Doug is somehow miraculously back in Episode 2 and Carley is nowhere to be seen.

Any help would be appreciated.

Save data might of been corrupted and it generated one of the characters in whilst you were playing episode 2. Could possibly have to restart and replay episode 1
