to further elaborate on the conversation in panel 6, if invisiblity was impossible, anything inside the invisiblity feild would be absent of any light, unless you had like a flashlight with you or something. so if you were invisible you'd also be blind.
but yeah, cale's little natation broke physics and he don't care
I'm not exactly sure, but I *think* it might actually be possible using a different method, which doesn't produce true invisibility, but creates an optical illusion convincing enough to pass for it.
I don't really remember the details of it, though.
(Also, "if your done" should be "If you're done", I think "we see on the horizon" should be "see it on the horizon", and "last I check" should be "last I checked".)
