"NCIS" season 12, episode 3 spoilers hint of danger to Ducky's life as flashback shows a much more dashing David McCallum.

The "NCIS" season 12, episode 3 spoilers were revealed through the synopsis which reads, per Cartermatt: "When an NCIS case reveals a connection to Ducky's estranged childhood best friend, he and Special Agent Bishop travel to London for interviews with family and co-workers of his friend. While there, Ducky finds himself reminiscing about the choices he made in his past and the subsequent impact they had on his adult life."

But someone doesn't really want Ducky and the rest of the NCIS team finding the truth and that someone has no problem with murder if it comes to that.

Earlier, "NCIS" season 12, episode 3 spoilers were revealed by TVLine as the producers and writes of the show will try to explore Dr. Donald Mallard's backstory.

"When we saw Adam, all we could think of was a young David McCallum. We can't wait to introduce him (Adam Campbell) as young Ducky and watch what he brings to this unusual role," Glasberg said.

Fans of the show would be delighted to know the origins of the bow tie and why Ducky is always seen wearing it.

The promo for the "NCIS" season 12, episode 3 titled "So it Goes" reveal Agent Gibbs telling Bishop that she will hop on the next plane to England. She then sees a photo of David McCallum as a young man and telling him, "you were hot," said Examiner.

It also shows that Ducky didn't always like bowtie since the flashback scene shows him being given a bowtie. He remarks: "Do I look like the bowtie type to you?"

"As for what's coming up in the present, Ducky reunites with Maggie, but they're going to be facing trouble - in the form of someone with a knife," the Examiner said.
