Investigate

You check the box, it isn't completely empty. you notice that there are several condom wrappers inside (no condoms though) though on inspection they are a bit odd. They must belong to one of your brothers (or maybe both you don't really know how close they are like that) but they are magnums, who knew. Also, you notice that each wrapper has been resealed like they were opened then sealed back up before use.

The tub starts to overflow and you quickly drop the box to attend to it forgetting about the puzzle abruptly.
