Mermaids are real

If according to Mista, human meat tastes bad because humans eat meat themselves, and if fish is good, then there's either even parts of human and fish meat on a mermaid, or it could be a new kind of meat that's between the two.

As long as they're edible, it wouldn't be too much of a problem.

Even though B has more fish meat.

Also, as we're on an island isolated from the land, A has technically more chances of escaping than B, as I guess B isn't that good of a swimmer without a tail. Depending on the size of the island, it would be much easier to catch B than A who can just swim away.

Given each are a perfect 50-50 mix, you'd be charged with bestiality for both.
Although, we need them to pass the test of Jack Harkness:

1- Are they as least as intelligent as a human?
2- Can they communicate their consent through clear language?
3- Are they considered sexually mature for their species?

Let's go with A first. If we admit A is a cute and funny mermaid like Ariel, we already have our answers.
1: We can't guarantee for sure the human head hosts a human brain, but it's quite logical.
2: We cannot be sure either, but there ought to be some use to their vocal chords, may it be for talking or singing. If there is a mermaid civilization or something, they have a language of their own. Whether it is more human or fish-like depends.
3: A is here pictured with breasts, so there again we can assume; but again, 13-year old humans also have breasts, so be very precautious.

Verdict: A is apparently okay, but let's keep a safety margin.

Now let's go with B. We don't have that much reference for landmaids, but let's try. For this example, we'll combine a Boston mackerel and a Caucasian human, and try to see what it would produce.
1: Contrary to popular belief, fish are quite clever. They understand social structures and have keen senses. Again, does that fish head host a fish brain? We can't know for sure.
2: B is here depicted talking in "fwap, fwap" onomatopoeias. Again, it might be a complex language system, but it is unknown whether humans can understand it.
3: Mackerels are sexually mature around three years of age. If the human legs present pubes or developed genitals, then B is of reproducing age. There again, be careful.

Verdict: B is much more trickier, but there can be more than meets the eye. Proceed with caution.

Conclusion: We don't have enough evidence to be sure, but we can determine that both A and B are able to mate with you. Caution is however required.
Note: Don't forget to ask for their consent first. If they don't explicitly give it, then it's illegal, regardless of how illegal it already was.


Then again, I don't see why we assume these fishpeople are only there for reproduction. I know that on a desert island, you quickly get horny, but does that mean ypu'd be ready to fuck a half-human?
You're desperate.

Depends on the person. A stranded asexual wouldn't care much. Or someone whose values are "do not fuck half-humans". It's like some moral rule straight out of Forumstuck.

Also, I am a furry and I'm not desperate.

I have nothing against furries, bro. I meant that you said fucking 'half-humans' is desperate, but don't furries fantasize about half-humans? So you're practically calling yourself desperate. This isn't an insult, by the way, just that you might have said the sentence wrong.

This the spirit of what I meant by "You're desperate". Like, chill out, it's not all about sex. It's nice but it's not mandatory. Plus, I doubt you'll have condoms on a desert island, and you definitely don't want to catch fishy STDs.

Also, about the intelligence point, I meant that since we can't know whether the inner organs match their outside halves, it's possible for the fish head to host a human brain. If A and B have equal humanity, then they'd also have equal intelligence.

What if the whole reason you're stranded on the island with the mermaid is for diplomatic reasons

Given that they're scantily clad, and the ambiguity of what "companion" means in this context, the assumption of eventual fornication is an easy one to make

So I get to be the ambassador that represents all of humanity? In that case, I'll apologise in advance for whatever it is I will inevitably do to fuck it up.
Although, if I wasn't informed of the secret diplomatic mission here, then perhaps the mermaid wasn't either. Maybe the human Illuminati and mermaid Gilluminati, working together, just stuck two unwitting weirdos together to see what would happen. The mermaid and I will discover the truth and form a crime-fighting vigilante duo who go around shutting down these shadowy secret organisations. So the question now becomes: In a buddy-cop scenario, which mermaid would you like as your partner? I will go with Mermaid-A, because I don't think Mermaid-B, with their fish mouth, will be able to spout the Bond One-Liners that are absolutely essential to being a action hero.

Guys.
