"Okay, but would earth even work?"
Sam looked up from where she had been scrawling into a notebook and gave a long sigh. "No, it wouldn't, Tuck. Not even a little."
"But, like, what if this ghost with sand powers comes up, attacks Danny and boom! Ice doesn't work," Tucker defended, waving his hands wildly to gesticulate his point.
"Still wouldn't work. Ice would freeze earth no matter its state; make it cold enough and even a rock could theoretically shatter from it," Sam rebutted as she wrote in her notebook. "Also, plants wouldn't work, as we all saw in the Undergrowth Fiasco."
Tucker shuddered. "Don't remind me. I'm still trying to wash the taste out of grass out of my mouth."
Danny watched the debate as he popped chips into his mouth, and asked, "Okay, but should I be concerned that we're debating what elements would go against my ice powers?"
"Not at all," his friends said at once.
Sam tapped the pages where she'd written down their previous discussions—air, earth and all their sub-elements—into it and said, "We're trying to figure out which elements ghosts could potentially have for their cores that could go against your ice core. It's just a way to prepare."
"Well," Danny said as he sat up from where he had been laying on the floor, "water would definitely be out. Ice is a sub-element of water, right?"
"Right," Tucker agreed, before he muttered under his breath, "Thank you, Avatar, for pointing that out."
"But light could be a potential element we need to watch out for," Sam pointed out, bringing the boys' attention back to it. "If a ghost with a light core produces enough heat, it could melt away Danny's ice."
"Same with a ghost with a magma core," Tucker piped up, before he smirked and pointed at Sam. "Ha! I told you a ghost with a earth-type core could go against Danny and his ice won't work against it!"
"But back to the light... I could produce enough ice that it could blind the ghost enough that they couldn't make the light hot enough to melt it?" Danny theorised. "So a maybe?"
Sam scribbled it down as Danny threw a chip into Tucker's mouth, the chip bouncing off of Tucker's glasses.
"Dammit," Danny muttered.
"What about crystals, minerals, jewels and metals?" Tucker proposed.
"Same as rock and stone. Glass would probably be in the same boat as well," Sam shot down, and Tucker slumped.
Danny patted his best friend's back. "Hey, at least lava could be a potential earth-like element we need to watch out for."
"True," his best friend said before he added, "What about electricity?"
Danny stiffened and Tucker winced, but Sam was thoughtful.
"Maybe," she muttered. "But Danny has mild electrokinesis already, so it probably won't work really well anyway."
"That, and I rather not find out if electricity does work against my ice," Danny muttered.
The three friends were silent for a moment, before Danny finally said, "Well, I guess there is an element we can all agree will definitely work against my ice."
As one, the trio said, "Fire."
And with that deciding antagonistic element, the debate was finished and Tucker suggested, "Wanna play some mindless video games?"
"Yes," Danny and Sam said in unison, abandoning the notebook to play a round of Doomed and be normal teenagers for a moment.
