Story advice pls help

So, I have a character who has a really big facade going on. In order to gain the trust of Ember, he uses a fake name. I'm debating if I should use a meaning for fire, to get Ember to trust him, or ice to give a hint on who he really is.
Help meeeeeee!!!!! So far Ember has two cats named Ashes and Flare. I don't want to go too overboard on the whole "Fire thing" but then again I don't know if ice is a good idea either.
Ugh!

Blaise is a fiery name, but it might me too obvious.
Mishal: Arabic name meaning “torch”
Aaden: Means fire/flames
Heti: Flame; Light; Fire
Icy names: Aspen (silvery tree), Jack (Jack Frost), Nicholas (St. Nicholas), Douglas (Douglas fir), and Whittaker (means white field).

As long as you're not overly up front about the name, it's not really a big deal. Look for names that mean fire or ice, not that sound like fire or ice. From there, I just suggest picking the name that sounds best to you.

That's what i was going for, something with the meaning. I just don't know which element i should use.

I'll see what i can find.

Thanks.
