As a general rule, when Viridian asks for help with testing something out - always use caution if you agree to assist.

The setup here looks likely to be one of her experiments. Her suspicious reply there almost guarantees it. These are the warning signs that point to mischief regarding this situation; that pressing that button may cause a shift in size for the user or some other type of change. What if this is just an overreaction to a situation that won't happen though, but then again - what if it isn't?

What should Trent do here; stop overthinking things and help out his friend, or save it for later and hear from the other folk helping out? It's strange how even the most innocent of things can lead to suspicion when Viridian is involved.
