To answer that question if you have the chance to watch the first 5 mins of last nights Hl's you will see why i think he took it to far.
Tom was asleep on the couch when Aaron entered the living area. Aaron made Tom a Brew and told Tom, your tea is there then walked away and said "Crikey". Tom looked up and said "What" and Aaron repeated "Crikey" only this time in a imo slightly antagonistic way
Crik-EEEy. Tom said, i said Tar, and Aaron said thats why i said Crikey, Tom said your saying Crikey because i said tar? and Aaron did a u-turn and said, No i said it because i looked at your face and saw how tired you looked. Tom then said you look great yourself sarcastically and that was that.
Aaron then walked through the bedroom door muttering "Stroppy little Madam"

Joined Faye in bed and Told anyone in ear shot Tom's in a foul mood about something, maybe he's just tired, i past him his tea and he looked at me and just shook his head and went Uh! Uh! then put his head back down, so okidoki!. The camera switched to Tom looking pensive and shaking his head.
So for me this is the first time i have actually clearly seen and been confident to define, a tactic Aaron uses in the BB house, some may say it's just getting back at Tom because he has been asking for it, and i wouldn't argue with that, key thing for me is, iv seen it before involving Jay.
The Motive
The wind up
then the misleading version of events to other hm's that make the other guy look like a nob.
So i'd be interested to know if anyone thought Aaron's game plan ran so deep as to include this passive aggressive type of interaction?
