Loki points out the Chitauri don’t have the Tesseract, so all the boasting from The Other is just farts. The Other gets ornery – Loki is ornery too, Loki makes the psychotic face- pointing out that he has the scepter – he actually did bring it towards The Other.  So that psychotic face I mentioned ( 4th image – his EYES)

He does this with Clint and Erik. He very vaguely hints that he would use the scepter – The Other gets even MOOORE ORNERY. – The Other flanks him and Loki just about loses his shit.

He reminds Loki.
