While it seems far-fetched to plan an explosion at the worksite, I think CW is capable of anything, so I'm trying to keep an open mind. And if NK and her friend were somehow involved, it does make more sense that they would want some kind of huge payout, like a settlement from Anadarko for negligence.
I've also heard a lot of good arguments for why it makes more sense that they were all murdered at home. So considering he pleaded guilty and that he might be lying about killing Bell and Cece at the worksite (which makes him look even worse), it does give the impression that he might be covering for someone.
But if Tammy and Coder were suspicious about NK, I wonder why they mistook what CW said about NK making him confirm his identity first via text, then telling him to delete everything and not contact her until "this is done". They thought NK suspected Shanann had his phone (which made zero sense since NK already knew SW was gone), when what CW actually said in the interview was that NK asked him the name of her (NK's) dog and what yoga studio she (NK) went to (probably because she thought LE might already have access to his phone). They also didn't bother to ask him what NK meant by "this is done". CW knew they misunderstood him, but he didn't correct them. Their mistake was carried through on the redacted transcript.

(With regard to if WATTS spoke to KESSINGER after the murders.)
He spoke to KESSINGER on Monday, August 13, 2018.
He and KESSINGER texted and then spoke on the phone.
KESSINGER said she believed SHANANN took off with his daughters.
On Tuesday, August 14, 2018, KESSINGER kept asking him “weird” questions through textmessage to try and determine if it was really him.
KESSINGER asked him what his dog’s name was and what yoga studio he went to.
It was possible KESSINGER believed SHANANN had his cellphone and she was making sure.
KESSINGER told him it was the last time he would hear from her and she was going to stay with her friend, JIM.
KESSINGER told him not to contact her “until this is done.”
KESSINGER told him to delete everything on his cellphone.
He didn’t delete everything from KESSINGER and he is not sure why.
