-He's probably not c/r bluffing the flop that much especially since he can't have the nfd.
- it's a small jam, and FE seems slimmish to an online regular

But:

-you have a J.
- he could maybe possibly have a worse J since it seems profitable to shove KJ here.
- You have the top of your range so you're making a ridiuclously explotable bet if you fold.
- He has shown the ability to get his stack in light.

I mean if you have really never seen him river c/r in thousands of hands i'd lean towards a fold. But i probably call cause its the mega-top of your range
