Probably more to do with his ratio of meaningful conversations in the house to times getting called to the DR.
Production needs to not be obvious about their DR favorites. Especially if they haven't socially acclimated themselves to the rest of the house.
It's idiotic of them and they ought to know better by now.
The Bomb Squad Alliance
The Core 4
Frankie - aka "The Diffuser", secret alliance with Zach & Christine, obvious alliance with Caleb, false alliance with Devin, socially gaming with everyone in the house
Derrick - undercover cop
Cody - Shane 2.0
Zach - hibernates during the day, games at hyperspeed when awake
The Muscle
Caleb - stalking/pining over/moping about Amber 24-7
Devin - whiner primadonna extraordinaire, hated by most everyone in the house including alliance members Christine & Cody
The Extra Votes
Christine - secret alliance with Frankie, joined at the hip to Nicole (not in the alliance)
Amber - stringing Caleb along, cleaning up after everyone
Their Preferred Targets (in order of priority for the coming weeks so long as they stay in power)...
1)
Donny (certified supergenius professor - aka not a groundskeeper - doomed if he fails to win POV)
2)
Jody
3)
Victoria (may not be pawned again for fear of her bawling her eyes out - seems like the house has had enough of that)
4)
Paola (should be OK if she survives the week but her pitiful challenge performances may keep her on the block for a number of Thursdays)
5)
Hayden
6A)
Jocasta or Brittany (I get the impression Brittany may be nommed solely to keep winning BotB comps if multiple HOHs collude as Caleb & Frankie did this week)
6B)
Brittany or Jocasta
8)
Nicole (extra vote in play thanks to Christine)
Incidentally, none of the above will play out because Devin & Caleb are awful and Frankie and Zach are over-gaming.
But there's some potential for it to remain entrenched due to the nature of the Battle of the Block twist.
POV is currently being played.
