Bruce didn't miss the flash of anger Jeff's eyes betrayed. He understood- using one of his inventions as a method of kamikaze would be a bastardization of its intended design. 
[color=0072bc]"I might take you up on that,"[/color] Bruce said, referring to his method of negating Ada's particularly devastating ability. [color=0072bc]"But I'm growing more confident that won't be necessary."[/color]
Bruce frowned, his mind focusing, or rather, returning to, the matter of the tower's interior. He'd been muddling over it for days, bothered by the sheer number of unknowns involved. The matter of the possibility that Bruce might be left without any way to use his earth powers left him feeling more vulnerable than the magic he and Jenso had encountered on their last mission together. 
[color=0072bc]"I've thought about it- and come up with a couple ways to try compensating. One's pretty unpleasant for me personally, and the other two might not be viable. I've tried manipulating metal before, but I can only sense things that interact with it, not control it."[/color]

Bruce caught the discouragement Jeff tried to hide and chuckled inwardly.
[color=0072bc]"It's easy to focus on what we can't do- but that only limits our imaginations, and that just restricts our potential."[/color] Bruce said, smiling a bit as he thought on how much he'd actually enjoyed practicing work with his Ki since his chat with Ross. [color=0072bc]"Mistakes are how we work toward success, if we learn from them."[/color]
Bruce tapped Jeff's shoulder with a closed fist.
[color=0072bc]"Don't be so quick to dismiss your role in the team. You can do things no one else can, and you've got a unique type of Ki- the things you could do are limited only by what you can think of."[/color]
A genuine smile crawled across Bruce's face.
[color=0072bc]"I can work with you during some of our off hours if it would help?"[/color]
