I've finally changed my mind - not Kirkland

It is Virgil

There since series 1.
Beloved character
right height
soft voice
stroke within CBI
Knows the systems and protocals(bugging offices/phones etc)


Importantly- time to do his dirty work and manipulate others from the comfort of his "self enforced" retirement
emotionally attached to Lisbon

I know Jane reached out to Virgil in S3 regarding JJ Laroche's suspect list.  Hmmmmmmm

woud be a shock

but for me

It is Virgil

ps..Lorelei never met him...just another proxy on RJ's behalf....maybe Haffner
