The Bad Guys know where Luke is now?

I would think so. The Falcon has a tracker which allowed Han Solo to randomly show up a few minutes after the Falcon left Jakku's orbit (what are the chances?!!) . So if the Falcon can be so easily tracked once, it can again - by the First Order.

Or here's an idea (copying the second film of the OT), the First Order dispatches thousands of probe droids across the galaxy to search for the hidden Jedi island...!

 

The probe droids makes sense.

Kylo did not find what he was looking for, which is when we cut to him whining like a spoiled child to Snoke about how powerful she is.

Rey didn't necessarily know that the island in her visions was where Luke was. But it was there for Kylo Ren to see, and he used it to taunt her instead of realizing he had Luke's location already.

 

Wouldn't the First Order be too busy with recuperating after the Starkiller?

 

This was what I thought at first. Since Han brought up that he had a tracking device on the Falcon, and said something to the effect of "If I could find you, so can someone else."

Then, without further explanation about the tracking device being removed/disabled, Rey is off to Ach-To in the Falcon.

 

seems moot if the intention is to bring Luke back....

 

It's NT a because the thing is if THE FO a would go there to bring him back or he leaves when he realizes that Rey briefly let skull into her mind .

 

I had a somewhat similar thought. Kylo knows that she's dreamed of a planet covered in ocean with an island in the center for awhile. S they could easily write in a scenario where Kylo and/or Snoke realize that those are actually premonitions dealing with Luke. Then it's just a matter of finding the right planet, or perhaps Snoke will already know where it is once it's described to him.

 

The only thing is that Luke Skywalkerr wasn't in that particular vision...right ?

 

He doesn't necessarily have to be for them to still figure it out.

 

How would you think they'd figure it out?

 

The second is correct. Rey had the info, and the first order would have been able to find Luke, if Kylo could read her mind, which he couldn't.

As for the tracking thing, i believe it is possible to, but i think it's unlikely.
- "tracking" something to a hidden secret base is kind of lame, and i kind of cringed when they did it in TFA.
- they could track the reconnaissance ship the first time because they knew they were on Maz's planet. The first order wasn't retreating because they were defeated, they left because they got Rey. I assume they were keeping tabs on the activity that occurred on and around that planet after they left.
- same could be said about tracking the falcon, because they know where the rebel base is, but i assume what happened after Star Killer blew up, is that Snoke ordered most of his forces back to where he is, like he ordered Hux to bring Kylo back.
- also because Luke's planet seems to be really special and sacred
