The salmon ladders back, and its sexier than ever.

Oliver races to Felicitys side and tells her not to move.
It also locked down the bunker, which Cisco designed to be impenetrable.
Its all very flirty until Curtis interrupts.
Chez Diggle, Curtis, Rene, and Dinah find John and Lyla mid-argument about her activities with Argus.
Good thing they kept Felicitys wheelchair in the bunker!
Oliver worries that Chase has discovered Williams location and decides to escape via the elevator shaft.
that Chase booby trapped it.
They get testy; see above, re: unresolved argument.
Shoulda listened to bae, bae.
Speaking of jump-starting (hey-oh!
), in a flashback, Curtis notices the longing looks between the other two residents of the bunker.
Curtis replies that they owe it to each other to see whats still between them.
Tonight, he emphasizes.
Then they argue over whos the bigger bad, Bratva or super-hacker Cayden James.
Before that argument can take off, the motorcycle engine causes an explosion that ruptures the methane gas pipe.
So much for doing things my way, Felicity sighs.
Oooh, does this mean theyll have to do ittheirway?
Hello, ofcourseit does!
She worries that her math might be wrong, and Oliver asks, Are you still Felicity Smoak?
She acknowledges that she is, and he says, Your math is always right.
Never leave us again!
She struggles, he demonstrates.
His hair looks great.
Her hair looks great.
She kisses him, he kisses her back.
Their shirts vanish, and the playful vibe fades when they stop kissing and simply look at each other.
Then Oliver picks up Felicity and lowers them to the mat, followed by a tasteful fadeout.
Lyla returns at this point with a copy of Curtis T-sphere courtesy of Argus.
Meanwhile, Olivers pulled Felicity onto his back and lowered them into the tunnel.
Then he collapses, the exertion having reopened his wound.
Felicity crawls over to him and throws herself against his chest, begging him to stay awake.
But he says he always trusted her; he didnt trusthimselfafter Chases torture revealed his taste for killing.
He confesses that his mission was based on a lie, then passes out as Felicity collapses against him.
Um, did they not have hours upon hours of bunker sex when they were together?
If not, whats even the point of dating a masked vigilante with a lair, then?
Felicity shakes off the post-coital glow and reminds him that their problems havent disappeared.
Oliver agrees and says its because theyve never discussed them.
She worries that Oliver hasnt dealt with the root of his trust issues.
I love you, but that is why I cant settle for anything less than your full trust.
So why not his own wife?
Before John can respond, Curtis interrupts to explain the plan.
You guys are sitting underneath a four-story bomb, Curtis says.
Theyve got 12 minutes to execute the rescue plan.
Olivers piggybacking Felicity to the rendezvous point when he collapses, blood oozing from his mouth.
She plunges it into Olivers chest without hesitation, and he comes to with a hearty, OKAY!
Nothing could possibly go wrong.
Felicity begs Oliver to let her go so he, at least, will survive.
Then Rene drags them to safety as I worry that all of them have irreparably damaged their rotator cuffs.
Also, Curtis temporarily fixes Felicitys spine chip so shes mobile again.
Flashback to the day after bunker sex.
Im not going anywhere, Oliver replies.
In the present, Olivers hair still looks great post-surgery, and hes thrilled to see Felicity walking.
This episode completely knocked him out of my brain.)
I understand why you lied to me about William, why you had to.
