Yesterday's presidential inauguration was littered with bizarre moments which quickly went viral online - including one which saw Barron Trump and Joe Biden shaking hands, and Biden's face appear to fall.
Now, a human behaviour expert reassessed footage of the pair's televised conversation, and has spoken out on what he believes was uttered between them.
The moment from yesterday's celebration saw outgoing president Joe Biden catching up with Trump's youngest son, Barron.

The clip has captivated millions of viewers since Monday's ceremony, with many spectators wondering what on Earth the duo could have been chatting about so intimately.
In the clip, the teenager can be seen at one point reaching for 82-year-old Biden's hand, before leaning in close to whisper something in his ear.
Whatever was said appeared to have hit a nerve with the former US leader, with the smile splashed across his face beforehand quickly being replaced by a rather solemn look.
Speculation has been rife ever since regarding their topic of conversation, with some outlandish theories having since spread across the web.

Speaking of Barron, one even teased on X (formerly Twitter): "Looks like he said, 'You’re done' lol".
Sadly, however, one body language expert claims their chat can't have been as interesting as it appeared.
Speaking to FEMAIL, communications guru Judi James began by explaining: "Barron very confidently and by all appearances charmingly bent to shake hands and exchange a few words with Biden."

"And although Biden's face seems to fall as though Barron has passed on some kind of sinister threat or message, the truth was less dramatic as Barron seemed to be leaning to greet Kamala and Biden's face was registering the fact that he'd finished his greeting ritual with Trump's son."
Judi believes misconceptions about the interaction have been sparked by the 'super-confidence' and 'humour' that the youngster appeared to be exhibiting yesterday, likely triggered by his father's return to power.
"When he was introduced by his father, he stood like a rock star acknowledging the cheers and chants of his name and even cupped his ear to increase them," Judi went on.
"Which is probably why people might assume (wrongly I'd say) that he's possibly making barbed comments on his way out here."

She added that the teen was 'working as a sweeper' on Monday, adding: "This means he tends to arrive and leave behind his parents but instead of just walking off behind them as he did when he was younger, he spends time shaking hands and offering gracious-looking words.
"This behaviour begins to define his personal presence and status but without compromising that of his dad's."
Judi went on: "He lets everyone know that he is becoming a force to be reckoned with in his own right and because of his height and the increase in his confidence signals, it gives him a rather princely air, presence-wise.

"The fact he does this behind his parents shows a level of trust from them, too.
"Biden had been on the receiving end of a flame-thrower speech from Trump, where he had sat in a variety of poses including pained deflation and bravado smiling as his entire four years in office were scorched to ashes."
