Hello,

Im inside Slaughterhouse in that part that i need to take 3 pictures to report IRIS. I take 2 pictures, but to take the 3 picture, i need that Double H break a gate, but Double H dont are with me a long long time. I need to know how I do to find Double H again.

Sorry my english, xP. Thx and bye.

I actually had that too once. Not in the slaughterhouse, but in a cave ( don't remember which ), and I spent half an hour looking for him, and then I finally found him by seeing a moving shadow on a wall... I thought. But he wasn't there, only his shadow ( ooh, creepy. ^^ ). Then, when I looked down, I saw him far in the depths of the cave running ( but not moving o_O ) next to the wall.
I loaded up a save file and he was with me again.

Anyway, to answer the question, I don't know where Double H is, but if you have saved, load up a save file and he'll be there, probably.
