I dunno why everyone thinks that jeremy has a thing for his stepmom.
You guys have read so many troubling relationships that you can't even see that they constantly establish that she sees him as her son and jeremy sees her as his mother...
He never touches her inappropriately, never crosses the line of anything above mother/son relationships...like please. Please open your eyes.
If you think him blushing when he gets complimented every time or when he receives a present, you might as well put that same logic towards her other kids.
