AJo Strange Flop Donk by Villian

[TheHammer24]

Villian is 25/6/2. His bets are instabets which kind of throw me off. What line do I take here?

Player between us is terrible Loose Passive

It's 6 handed at a ten handed table, but I posted it here for it is mulitway and a ring game that is playing short.
