I sympathize with your "potty mouth." We had similar experience with our first child, when he was 3. We were driving somewhere with my aunt and uncle, and our baby starts saying dumb f**k over and over. Horrified, my husband, who was the potty mouth in our family, looked at me, then at my aunt, and said, "He said dump truck." Yeah. Dump truck. LOL! I gave him points for quick thinking. With children grown, I don't watch it now, but should, since sometimes your #2 slips out. :-)
On a more character based discussion, I do think alpha heroes curse. A touch hero who says "darn!" wouldn't work for me.
Love your covers, have the books in my enormous TBR pile.
