The fiery $50 million defamation suit between celebrity exes Johnny Depp and Amber Heard continued Monday, with an expert witness claiming that the Pirates of the Caribbean actor displays "consistent behaviors for someone who is a perpetrator of intimate partner violence."

During the trial's final week, Dr. David Spiegel of Virginia testified that Depp exhibits several traits that are consistent with precursors or risk factors for intimate partner violence.

"Mr. Depp has behaviors that are consistent with both someone who has a substance use disorder as well as consistent behaviors with someone who is a perpetrator of intimate partner violence,” Spiegel said.

The witness claimed that he isn't offering an "armchair diagnosis" despite never having evaluated Depp because "I have reviewed a lot of professionals and the evaluations and their treatment course, video depositions, picture deposition, court filings, emails. I’ve reviewed a whole lot of things that describe Mr. Depp and his behavior.”

Examples of traits that could be both risk or precipitating factors of domestic violence are "having someone in the relationship who is jealous or suspicious," "having someone who has a higher than average acceptance of violent ideations," "someone who has rapid and extreme mood shifts," and "someone who has limited self-control," Spiegel said.

Throughout his testimony, Spiegel referred to Heard as a "victim" and noted that he doesn't expect those who are subject to abuse to be perfect either. He added that victims sometimes have their own diagnoses.

Dr. Richard Moore, a hand surgeon, also offered an expert opinion, this time on the actor's severed finger.

According to Moore, it was unlikely that the injury Depp sustained could have been caused by a thrown vodka bottle, which the actor claims occurred.

Moore noted that Depp's nail was relatively intact and that he wouldn't expect it to be so if the injury had occurred as he described.

"It's not consistent with what we see in the described injury pattern," he said.

"The description was the hand being flat on the bar and the bottle crushing the finger from the top. But looking at the images, there's really no significant injury to the dorsal of the finger and created the type of injury," Moore added. "We would anticipate both injury to the fingernail and other parts of the finger."

Gory photos of Depp missing a chunk of his finger were once again displayed for the jury.

"This wound doesn't really appear to be a sharp glass laceration," he said, explaining that there were no glass pieces embedded nor were there other lacerations.

"My testimony is that I can rule out the injury as caused by the mechanism described by Mr. Depp in his deposition," Moore said.

The actor's team noted that the witness had never examined the injury in person and has similarly never treated Depp.

Depp is rumored to take the stand once again on Monday.
