This is from Christopher Priest's 2016 Deathstroke run, it's also called "Prieststroke". Honestly, this run does what it wants & strives to do best, showing Deathstroke being an absolute cunt of a human being. So, unlike the one before, this one was done out of sheer purpose.
Just the basic gist is, Deathstroke's son, Jericho (Joseph William Wilson, aka Joe, aka Joey) got himself a Haitian hottie named Etienne (aka Eddie) for a fiancee, except Etienne was a spy that was sent by Amanda Waller to spy on him & Deathstroke. Except she wasn't even Waller's spy. She was a triple agent working for HIVE (Adeline Kane), much like Louis (Richard/Apogee).
Adeline sent her to spy on Waller as a mole, or turned her while she was working for Waller, then Amanda sent her to spy on Deathstroke. Slade knew this, which is why he seduced her, but didn't reveal any sensitive information about himself. Yup, instead of telling his son something like "I love you, Joe. Here's some advice ..." , he fucks his son's fiancee because she was sent to spy on him by the government & he thinks that if he fucks her, it will make Joseph cut her off. Yup, Christopher Priest Deathstroke (aka Prieststroke) literally cuck his own son Jericho (aka Joseph Wilson, aka Joey), with his son's fiancee Etienne.
This first panel will make more sense later on, it's even more retarded than the cuck son side-plot.

It's not even a one & done deal either, he keeps at it, even doing it while she's talking to his son on the phone.

>Cucks his son.
>Makes it her fault.
Now, explain that first panel, see, Joseph was (emphasis on the WAS, later) with Isherwood for a few months & then was with Ettienne (Priest confirmed this on his blog), with who is essentially is uncle & his father's war-buddy & partner Doctor Ikon. Yes, Joey was bisexual in Priest's run. He made it clear he wasn't gay & didn't care much about body parts with the people he dated. The Jericho/Ikon couple is supposedly used as a parallel for Slade/Terra & had Slade call Ikon out later.
Well, now for that
WAS. It was until he tried to murder him for his suit but then Joey felt so guilty it made him suicidal & then he tried to resurrect him out of a coma. Also they met when Joey was a teen.

Anyway, it gets worse, Waller wants to end the charade going a bit too long with the marriage & shit, Etienne finds out about the SayUncle fag affair going on randomly, & Slade wants to use her however he wants. Eddie just tells him she's banging Slade behind his back, & a lot more.
Also, Slade is blind, which makes this panel funny

She technically cucked herself, this is a cuckseption. A "Keicucku", if you will.

Then, this was the end of this Volume (#17)

Just to clarify, this
wasn't done by either Jericho or Slade. This was done by Rose's split personality, Willow. She killed Etienne before the wedding. It wasn't Rose's fault & Dr. Vill (Will Hane), later explains it. Her brain takes the information she knows, & works overtime to create the most likely sequence of events to occur based on what Rose wants to do next, & her state of mind. She wanted to kill Etienne, & envisioned her dead, her brain then created the most likely scenario of Etienne's murder. It came to her as a nightmare at the Hmong family's home. Willow & Rose seem to be aware of each other's perceptions, as Willow killed Etienne for Rose, and Rose spoke Hmong to Red Arrow once.

.
Afterwards, Slade hired a bunch of actors to pretend to be his daughter's family from her mother's side. But Jericho finds out about Eddie's death & seethes. He tried to kill Slade, Rose tried to help Joey, & got punched by him. Slade & Rose lived, & Joey went to rehab. I'm not posting pics of this I'm getting tired writing this.
I will post one last thing tho, which is this funny interaction about this whole thing later on (I think around Volume 2

in the run.

>Can you please stop bringing up your fiancee I banged, son?
>Yes, I fucked your fiancee, yes, she's dead now
>She died & no one cares
>Yes, which should tell you something.
I'm not telling you what happened in this run before, & what more happens in this run later. The main point was Priest's love for cuckoldry & infidelity arcs.
