(said silently...) "Move your chair towards me...You have my word!"

"I'll sustain you, Ukrainians...freedom fighters for us."

The chair of the speaker was already stilted in Zelensky's direction, as the whisperer had indicated. 

"Then be of stout heart."  Chancellor Merz continued in hushed silence,  "The purpose of us EU members here with you this day has been accomplished."

And a chorus of  voices could be barely heard as chairs of all the other EU members present tilted ever so slightly towards President Zelensky's.  (In hushed unison, their saying,) "AMEN."  

My imagination.
