Sure Maggie does what she wants to do since she's a grown woman; but she's putting THEIR child's life at risk. Since Glenn's the father, he definitely has a say into whether he thinks it's safe for her to go. He didn't seem to have a problem with it...good for him/them.

All I'm saying is that if it were me, I wouldn't be comfortable with her going knowing the risks involved and would try to convince her to stay.
