It's your best friend the Companion Cube! Incinerating it is an option, but remember, if you decide to incinerate the cube, there is no turning back (except of course restarting). Don't break its heart! The orange portal is kinda glitchy, it waits a second before transporting the cube to the blue portal. Oh, and we remind you that the companion cube will never threaten to stab you, and, in fact, cannot speak. If it does speak, however, please only answer its questions with yes or no :) Press the button (invisible) under the aperature emergency incinerator! ;)
