A couple odd things

[kickair8p]

A couple odd things I haven't been able to figure out for myself, hoping you guys can help:

• The horned animal skull on the wall with the headphones -- what species is it?
  
  
• During John's war-nightmare his name is shouted a few times, then right when he wakes up there's two echoing syllables -- I can't make them out, and the subtitles didn't catch them.

Thanks!
