I was thinking that after this thing with the Robot, Batman could go and investigate and/or have a "Chat" with Lex Luthor, since I was thinking that the thugs he was interrogating on the roof during the OP could have been smugglers that were sneaking disguised Lexcorp weapons to radical elements in Khandaq maybe?

I feel like it makes sense for a weasel like Lex to be secretly playing both sides for maximum profit.
