I do not think they have an interest in Tanya. I think it was just a coincidence. She was there so Randy grabbed her for fresh meat for the grinder.

Alt twist.. Tanya becomes scared and Hulks out and rips the little one to shreds and then turns back to good ole Snippy Tanya.. Victor just stares off into space for several days not believing what he just witnessed..

What I think happens.. They miraculously get a away from the little in time to toss an air take at it and as soon as it picks it up Vic shoots it Jaws style and blows up #7.. Then its mama comes back looking for revenge..
