In Attack on Titan, the Survey Corps managed to capture two Pure Titans, named Sonny and Bean by Hange Zoe, after the battle of Trost. These two titans were later killed in the middle of the night by Annie and Reiner to prevent the Survey Corps from gaining further knowledge about the Titans.
After the two Titans were killed, the Survey Corps carried out a full inspection of all the members' ODM in an attempt to catch the culprit (presumably to check whether they had been recently used). Annie managed to escape this inspection by presenting Marco's gear instead of hers, but how did Reiner manage to escape this inspection? Was it ever revealed in the manga or anime as to whether Reiner perhaps used another set of ODM gear?
The image below is taken from Chapter 97 of the Attack of Titan manga and it clearly shows Reiner having his own set of ODM gear, but the manga does not explain any further as to whose gear that was.
