Now see, guys, I didn't take it that way. I think EG was trying to establish that Lucas was an active, gung-ho little boy who wanted to be part of the action. (Not saying I believe that to be true, though.) Telling one child to be careful would not preclude saying the same to any and/or all of them. She just was talking about Lucus specifically, not the other kids; kinda "Take it easy there, kiddo! Calm down!""
My family never had any problem telling everyone to chill when the group started getting "rammy," as we called it. I think a lot of times what we're picking apart is just how people speak colloquially.
Hope that makes sense. No way no HOW am I defending this person at ALL. It's just that when we start ascribing EVERY possible nasty word, deed, or intention to EG, we run the risk of creating a character profile that is more a Snidely Whiplash caricature -- and a list of "facts" that is sometimes impossible to separate from fiction.
(O/T: +10 if you know the name of Snidely's sidekick)
