That is soooooooo correct.Mind linking is totally cool concept of the pair actually. Way cooler than Astral Projection of other legendaries.
But you would only be invisible for a few moments, until direct sunlight hit you. Pretty much how Latio and Latias appeared in the movie when they were exposed to sunlight.
Well, yeah but.... (starts thinking) I got no argument. XDWell, if they are exposed only to sunlight for a second or such, everybody would just think of it as as trick of the light and such. However, if they are exposed to it a second longer, I'm sure people would care. Latios and Latias isn't exactly the most common of the pokemon.
Guy: *saw a latios* Oh, cool. Latios.
No, Lati@s are legendearies, and I am sure people would care.
