Here's my deal.
The Scot knows that Unser is in contact with Juice. NOBODY TAILS UNSER. Stupid. So stupid.
The Juice scenario should play out like this: Juice ties Gemma up and leaves her in the woods somewhere, alive. He takes Gemma's cell phone, which he absolutely has access to now, and he calls Jax, he explains everything. Gemma killed Tara. Here's where Gemma is. Go find her and ask her yourself, Jax.
I think Nero will end up killing Gemma. The Chinese are almost certainly going to kill Nero's kid as a payback for his betrayal. Nero will get pissed and grow more and more suspicious of Gemma, he will discover the truth through Juice, Nero will tell Jax and then Jax will give Nero the OK to kill Gemma. Roll credits.
Observations!
-I love Jimmy Smits so much, but brother you're a little to old to be wearing such tight ass shirts. He's in great shape, don't get me wrong. But it just ain't right dude.
-My favorite part of Nero and Jax fighting is them portraying the two as physical equals, even though Nero is a man sized 6'2" or maybe bigger and Jax is like 5'8". Not since The Rock fought Vin Diesel have two such ridiculously mismatched men (physically speaking) faced off and had the whole thing portrayed as if they were equals. As a matter of fact, 5'8" Mackey used to intimidate 6'2" Dutch, so maybe this is just a fetish of Sutter's.
