Oh my God, in the DS9 novel "Station Rage", there's a scary invasion situation coming to the station, and Garak tries desperately to trick Bashir into going down to Bajor, to get him out of danger???
The station has been largely evacuated but the department heads have to stay, and Julian insists that anyway he has to stay (and wants to stay) to treat any casualties.
So Garak lies that Sisko had passed a message through Garak that they need Bashir down on Bajor to figure out the source of a medical emergency.
And then, and then Julian figures out it's a lie, because, after passing on this supposed message... Garak lingers too long. Because he's concerned. And that tips Julian off.
'His natural clairvoyance' - aka goddammit he knows me too freaking well.
As echoed immediately by:
Julian can read him, dammit.
AND, a point I think is true and huge: Julian is the only person to have approached and treated Garak like Garak is an individual. He absolutely knows that Garak is a scary spy dude, but he treats that as a facet of Garak, not the sole definition of Garak. Julian has always treated him entirely differently than anyone else has.
Then Garak tries to be all armoured and sharp to hide his anxiety and his deep, personal concern, but he's completely transparent to Julian who is just like, "Yes yes, you adore me, I adore you too, duh, but back to the whole tricking me off the station thing?".
So Garak is just like 'ah crap none of my sneaky attempts to get him to safety worked, not even my attempt to hide my feelings worked!' and just gives up trying to hide his emotions, and is openly like 'I neeeeeeed to get you off the station and out of danger'
