Well, I have a few questions if you don't mind. I'll try not to repeat anything already asked so bear with meh~

1. Active powers aside will elementals have passive traits that are common to all members of their element, for example being aware of the presence of their element in their surroundings. Or water elementals knowing when/if it is going to rain. A mixture of harmless/useful stuff like that.

2. I assume that since elementals live in secret alongside humans we are more or less completely human in appearance. Is it possible to have slight physical traits that allude to our heritage, ones that can be hidden? Traits that might also suggest our 'beast' form should we ever go down that route perhaps?

.....This has nothing to do with me wanting a fluffy elemental tail...

3. If elementals do come to blows, not saying this is my intention but you never know, is the course of battle dictated purely by the ability/power/control of each combatant or does the element play a role as well, as in does fire possess and inherent advantage over ice, ice over water, water over fire etc?
