Well, to clarify or muddy the waters further... however you want to look at it.
I think the coin flipping is even more out of character after you described her. She doesn't seem like the type of person who would need to flip a coin to decide to go. I do like the free spirit it implies... maybe she flipped the coin to decide which direction? That might be fun to work into the verses.
Ah. I see. OK, the direction I'm seeing this go with the verses is her many tosses of the coin. The many times she paid the price for speaking her mind , or even just having one. So. I was seeing her as a kid and weighing up the cost of talking back to an **************************** teacher. Are we ready to flip this coin? Deliberating... still holding sir... and... go. "From what I understand, the earth is much older than the bible says it is." "It's just hair color!" "But I don't like to wear dresses!" And forever branded a trouble maker. The cost. Worth it at thrice the price. So, the coin motive will hopefully be used more in the verses. Maybe, I hope, kinda.
So she is the type. Always weighing the cost of her big mouth and the truth.
