 During Buds descent into the abyss, the pressure beings to affect him and   his link with the surface. In the original film when the crew realizes   something is wrong, they ask if Bud can still hear them, and his typed   response is just gibberish. A brief new bit of dialogue has been inserted   just before this: Bud types "youre going away" and Linsdey replies "No Im   not, Im right here, Bud."
