Question: Just wondering about something. Thanos sent Loki to Earth to recover the Tesseract, which contained an infinity gem. To do this he gave Loki a sceptre, which also contained an infinity gem. When Loki failed in his mission the sceptre was lost, so Thanos not only didn't get the Tesseract Gem, but also lost the Mind Gem, which he already had? Or did he not know the sceptre contained an infinity gem when he gave it to Loki?

Chosen answer: He knew. Most likely he planned to kill Loki after he conquered Earth. This is just speculation. We won't know fully until "Infinity War".
