The catchphrase game

[Muizer]

Once you mentioned species, it clicked.

Cloud cuckoo lander, meaning someone way out of touch with reality.

That's the one

[Sar1n]

Sorry, I had some internet trouble...

All's well that ends well.

[Sar1n]

Too easy I suppose. Oh well, over to you.

[Septentrionalis]

No matter, these are hard to get just right. Let's see how badly I fail:

[Septentrionalis]

Hint time. The expression incorporates the word "no" that is not represented in the images. I thought it would get too easy if it did, but I may have been wrong.

[Kilo11]

I am stumped. Would you mind throwing us another hint?

[Septentrionalis]

Of course I don't! The first picture is from Fallout: a Post-Nuclear Roleplaying Game. Spoiler concerning the game ahead; I'll give another one right away if any of our participants is going to play this for the first time.

In the end, the protagonist, Vault Dweller, saves the Vault, but he is exiled because his adventures have changed him so much that he might be bad influence to the others. This is him right after being told to get out. So what is he doing?

[Kilo11]

Hmm... I thought that was either 76 or Fallout 4. I wasn't certain though, and I also wasn't sure if I was supposed to think Fallout, or rather just think wasteland (or even desert). With your hint, I will think things over though, as I feel I've now got something to go on. Maybe I'll have a proper guess tomorrow...

[Septentrionalis]

Okay, another hint. The last pair of pictures is really key in the sense that even if you only guessed that, you could guess the rest. It is from the Walking Dead, and has to do with the parlance (terminology of sorts) in the show.

[Septentrionalis]

I wonder if anyone is onboard this anymore. The black and white picture in the middle is the logo of a clothing brand; the logo itself has a name that is relevant to the mystery. The name could be guessed by the picture alone, but it probably helps that I point that out.

[makanyane]

The logo seems to be from Volcom clothing brand - but that's certainly not helping me...

[Septentrionalis]

Great, you are on to it! And the logo is called Volcom what? Nice to see participation.

[Kilo11]

Okay, so I don't have a guess, but here are the things I have in mind (in case that helps others).

Picture 1: leaving
Picture 2: the stone
Picture 3: the undead

Sept also said "No" is somewhere in the expression. Some potential notions that came to mind were things like "Not leaving the stone to the undead" or "Leave no stone....

Got it. While writing, I think I figured it out. "Leave no stone unturned." I've not seen Walking Dead, but just realized they might call zombies "turned" or something.

[Septentrionalis]

Good job, Kilo! Indeed, it is called turning in Walking Dead. I admit that I considered myself a clever little chap for coming up with that pair of pictures (pride and vanity!), but as it is with these, it is hard to get the difficulty right.

On to you!

[Kilo11]

Had to put in the work, but it was worth it

Anyway, here is the next one. I've left some words out, but I think it should be very doable even without them.

[King Athelstan]

Cry havoc, and let slip the dogs of war

[Kilo11]

The King has it. And how did you like the doggos I chose? I thought maybe the ridiculousness of associating a couple of Pomeranians with that expression might throw someone, but apparently Athelstan thinks of war when he sees those tiny fluff-balls. Who'd have thought?

Anyway, the floor is KA's.

[King Athelstan]

There is nothing more warlike than tiny dogs.

[Septentrionalis]

Per aspera ad astra? Soar like an Eagle?
