I'm not picking on you, just selecting one of many possible posts on the topic to address the question. Where is this source coming from that Chad and Lori are/were sealed in a temple? Or is it just speculation and rumor?
Personally I believe this whole temple thing is way off base and completely the wrong direction to be looking. And as evidence I point simply to their beach wedding - which is on record and we have proof of.
Consider this. If somehow Chad and Lori were able to procure a temple sealing (and it's a huge if, but let's entertain it for a moment), and they truly believed they were now sealed together, then why in the world would they then go and have a beach wedding? It simply wouldn't make sense. No, the fact that they had a beach wedding is evidence that they couldn't and didn't have a temple wedding/sealing prior. And the fact that they've been on Kauai or Maui since their beach wedding is evidence they haven't had a temple sealing since then.
In addition, all photographic evidence depicting her modesty standards suggests Lori is not an endowed member of the Church, or if she is she's not living up to her covenants. Which means she wouldn't be able to enter a temple anyhow. MOO.
