Whiffed AKs on wrong monotone flop

[registrar]

Final two tables in $20 1r+1a

Villain was at my first table. He open limps a lot with any stack size and has doubled up with AA thus. At that first table, I was pretty laggy and donk doubled through him, calling a reraise from BB with AJ and calling his check-raise push, turning trips to beat KK. He hasn't notably defended his blinds, but I was pretty laggy early and I've been pretty laggy since he came to the table.
