Tuesday proved to be the most dramatic day in court yet in Donald Trump's civil fraud trial in New York.
The former president found himself face-to-face with his former lawyer and sworn enemy, Michael Cohen, as he testified for hours about how Mr Trump allegedly "arbitrarily" inflated the value of his assets.
A judge has already ruled that Mr Trump overestimated the value of his properties to secure favourable loans, but a trial will determine the damages he must pay.
New York Attorney General Letitia James, a Democrat, is seeking a fine of $250m (£205m) and a ban on Mr Trump doing business in his home state.
Mr Trump has repeatedly denied any wrongdoing, arguing that his assets were actually undervalued. The former president has been occasionally attending the trial on a voluntary basis and is expected to testify at some point.
Here are some of the key moments from the day in court, which saw Mr Trump and his fixer-turned-foe in the same room for the first time in five years.
Among the most startling revelations, Cohen claimed that Mr Trump would ask him to "reverse engineer" assets to increase their value based on a number that the former president "arbitrarily" picked.
He said he and Trump Organization ex-CFO Allen Weisselberg did "whatever Mr Trump told us to".
The pair would work until they reached Mr Trump's "desired goal", Cohen claimed.
Mr Trump could not directly respond to Cohen's claims in court. He appeared to look in Cohen's direction, but said nothing as his former attorney took the stand.
Instead, the former president used several court recesses to discredit Cohen, who he said was a "proven liar" and a "felon".
Cohen – who once stated he would "take a bullet" for Mr Trump – was given a three-year jail sentence in 2018 for lying to Congress about hush money payments he made on Mr Trump's behalf.
Tuesday's testimony also featured several unexpected characters: the Buffalo Bills football team and singer Bon Jovi.
In 2014, Mr Trump reportedly tried to buy the NFL team based in upstate New York.
But his bid fell apart – and proved to be a key line of questioning for prosecutors on Tuesday as they sought to show an instance of how Mr Trump inflated the value of his assets.
When the Bills were put up for sale about 10 years ago, Mr Trump reportedly found himself in a three-way bidding war with the owner of Buffalo's professional hockey team as well as a group of Canadian investors who had teamed up with Bon Jovi.
The war turned tense, with Bon Jovi critics trying to block the singer's bid, while Mr Trump reportedly hired a Republican political operative to try to stop his rivals.
Cohen claimed the bidding process also proved fraudulent, testifying on Tuesday that Mr Trump used a financial statement with inflated assets to prove he had the funds to purchase the team.
It did not work, a point that Mr Trump's lawyer, Christopher Kise, argued made prosecutors' line of questioning irrelevant to the case.
But "because fraud was not fully perpetrated" does not mean it was not relevant, the prosecutor argued.

While Mr Trump remained quiet during his day in court, sparks flew between Cohen and one of Mr Trump's lawyers and fiercest allies, Alina Habba, who tried to paint Cohen as a serial liar.
During cross-examination, Ms Habba paced back and forth in front of Cohen. She grew frustrated as he answered her questions in a lawyerly way instead of offering a direct "yes" or "no".
At one point, New York Judge Arthur Engoron, who presides over the trial, asked Cohen to simply answer the questions.
Testimony turned even more tense after Ms Habba asked Cohen if his wife knew about his tax evasion, leading to a brief outburst from Cohen.
Another Trump lawyer, Mr Kise argued Cohen was "completely out of control", sparking laughter from the courtroom.
As Ms Habba continued her line of questioning, she continued to take aim at Cohen, saying: "you're not on your podcast… you're here with me".
She will continue her cross examination on Wednesday, when both Mr Trump and his former employee are expected back in court for what Cohen has called one "heck of a reunion".
