(Chickenlady, not knowing your age, and dont feel the need to tell me. That's not info to be sharing online... i cant really say whether you've been 16 or not. However, i have IRL 4 kids under the age of 10. Not one of them would be throwing tantrums and especially not hurting an adult when they didn't get their way.
Because they know, 1. they won't ever get what they want acting like that, and 2. if they want to be treated with respect they will act respectfully toward others.
Ella being excluded from going into a life or death situation is not because we are trying to exclude you chickenlady, but that the characters have no reason to trust she wont start screaming in a life or death situation over something trivial.
Keep in mind that our characters are not us, we are portraying created characters who will respond to other characters based on their interctions. It's actually frustrating to me to see River(the character) being such a pushover to toward Ella. I know her character well, and trust me she's being an angel compared to how her character should be reacting to yours.
Now all that being said, there really is nothing stopping your character from completely ingnoring everyone and following them, however if ella goes inside the tunnels she has no powers the pure know about ella, and Izzys powers and have protected themselves from having things stolen.
There WILL be fighting inside. Your character could get hurt.
If you would prefer you could have her decide to go to the other group. Alice and a few others are 16 so they should at least know of each other, and they would have seen each other the night before at River's house.
I will tell you though that Alice isn't going to put up with a person that stomps and screeches when she doesnt get her way. 16 year olds don't.... or shouldn't do that. My IRL 4 year old doesnt do that.
I'm not saying this to be mean, it's to reassure you that we, all of us, aren't trying to be mean.)
