Shakespeare would have been proud of young Kira. ("but at the length, truth will out." The Merchant of Venice.) Once again, Kira's motives, born of innocence and truth found a solution to everyone's problems which led to unfettered sacrifice and and the gift of compromise.
Upon hearing the conversation between Sarah and Cal, Kira took it upon herself to bring clarification to the plight of Cosima. Her selfless act should not have been a surprise to anyone by now. Well, perhaps Cal and Sarah. But as we the viewing audience know, Kira possesses faculties beyond her years.
Her act shone a light on various other acts of sacrifice or compromise. Some of which were also born of a truth that could remain hidden for only so long.
If we call Victor, "Vic the Dick" then shouldn't we call Donnie, "Donnie the Dupe?" The truth did certainly come out for poor Donnie. When he learned of his misbegotten treachery he looked absolutely devastated. Do you suppose he had flashbacks to the wax torture treatment from season one? Now he knows the reason behind all of Alison's pain and mistrust. Imagine the weight of all his sins rushing at him at once. All because he thought he was doing the right thing. Now he must live with his acts.
The man that led Donnie down the path of lies now sits crumpled amidst a blood splattered tableau. While Kira's moment of truth led to sacrifice, Leekie's truth led to his lies catching up with him. How ironic that Leekie would die at the hand of the man he led astray for so long! Donnie's act was typically clumsy. The poor sod just can't win. (Who will he call? Alison? She's adept at skipping out of bloody messes.)
The connective thread that led to Leekie's flight into the night came from another act of truth when Rachel learned of the circumstances of her youth. Her father was actually alive and the man who raised her was exposed for the liar he was.
But instead of having Leekie killed, she actually showed mercy upon him. It was if the few years she spent with the Duncans was enough to overpower the many years of deceit at the hands of Leekie and the repressed, vengeful Rachel was reborn into the calmer loving child she once was.
Maybe the truth does set you free.
Rachel's transformation evolved from a similar act of faith and truth. Siobhan stepped into the lion's den armed with the truth behind her knowledge. She confronted Leekie which eventually led to Rachel meeting her father. Her knife edged compromise with Paul from the week before led to this peaceful understanding. Siobhan took a big chance but her willingness to compromise may have set many others free.
Alison also decided to follow the path of truth when she confided in what she thought was a kindred spirit in Vic.
Much like Leekie, Vic nearly met with a disastrous fate when he face planted himself into Alison's craft kit. Pity he couldn't handle the truth as Sarah did when she decided to sacrifice a bit of herself and agreed on meeting Vic. Sarah knew she had to make certain compromises in meeting with Vic if it meant freeing Alison.
"....And you will know the truth and the truth will make you free."
Odds and ends.
I'm not so sure Marion is a believer in the truth. And I doubt she is any hurry to set anyone free. At last Michelle Forbes is on the scene. It took a while for her to get here but she looks fabulous. We now have a bigger bad and I wonder what secrets she holds?
Marion definitely outranks Rachel and with Leekie out of the way there is no one to protect Rachel's back save Paul. (And I am not so sure about that.) This may give Rachel the opportunity to join Team Clone. I can definitely see Rachel switching sides although she may want to play it safe at the Dyad institute until she gets the medical results she needs. A power struggle should ensue with Marion but if Rachel plays her cars right she may get the power to unseat Marian if not provide the other clones with the cure they so desperately want.
BTW, does anyone else sense a biological connection between Marion and the Clones?
I should have thought to look for more of these but as we can see above, Sarah looks lovingly upon Kira when they were reunited.
Similarly, Delphine shares a tender moment with Cosima just before her procedure. (We could even throw in Leekie bending towards Rachel when he offered her a goodbye kiss.)
One last pic! I call this, "The Dynamic Duo cart off the Joker."
