Hmm... I'm torn between option 2 and 4. They seem quite challenging to me.

Honestly, I can't even imagine having a valid reason for option 2. Unless perhaps, there was this force that made saving one twin much easier than the other. Or unless the other twin was a brat or something like that. But if neither was the case then...it will probably be the hardest decision of my life.

Thanks G-dog, now you've given be a lot to think about....
