Who is he rescuing ?

Jed is always talking. He talks all day and at night too when he is sleeping. Last night he was fast asleep and was having a long conversation. I caught a bit of it and he was saying "I'll rescue them." I wonder who he is rescuing and also wonder whether "rescue" is normally in the vocabulary of a 2 year old. He sometimes calls Emma a "rescue dog". So maybe they were working together last night.
