His “big plans” are…
—taking her home to meet his parents? (Mom just made parole!)
—playing bingo at church? (Grand prize? A life-sized crucifix!)
—watching sexual hygiene shorts at the asylum? (Two-for-one night if you have a split personality.)
Or maybe he has something even more exciting planned.

If he were in the navy, I would guess he’s planning to cross her equator. He looks to be an Army man, though, so he’s going to show her how he stands at attention.
