"How strong of a preference that is? We derive a lot of versatility from switching powers around."

"We'd prefer you not use untested abilities on stealth missions. You don't know that they'll work as advertised. Not everything is going to require thorough testing - but something that'd be the lynch-pin of a stealth attempt is more important to test."

"That's reasonable. We were already keeping some powers... ah, pinned. And it's easy enough not to use them or inform you before hand."

"Glad we can see eye-to-eye on this. We'll try to make the testing as painless and short as possible. Very few people enjoy that part."

"How likely are they to be painful or inconvenient?"

"It's more tedious than anything, and it's very likely to be that. You'd be trying to maintain stealth around people with various perception abilities."
