Need urgent help with back windshield

The back windshield of my 2011 prius starting vibrating/rattling last night. I know the only proper fix is to take the whole glass off and re-seat it again after applying the adhesive.
What i need is at least a month long temporary fix which would stop it from rattling and/or make it reasonably weatherproof.
P.S. only 1 corner (upper left side) is detached.

 

wish i knew. upon closer inspection, i did find out that that the adhesive bead was laid in "sections" (not a single bead going around the glass). 1 of the sections has broken free of the metal. there is no adhesive sticking to the metal, it's all sticking to the glass. I also did not see any primer under the adhesive.

is there any way of checking if the windshield came with the car or was replaced be a previous owner? and if the glass is OEM, is toyota liable to fix it free of charge (car is obviously not under warranty anymore)?

 

got the glass resealed at a-line auto glass for $195. safelite and others that i called refused to work on the same glass, instead saying that they can only put in new glass which would be over $400. figured out what went wrong, when some previous owner had the hatch replaced and painted, the paint gave up and was stuck to the adhesive.
