Going out for some UFO watching/investigating a haunting/other strange shenanigans. Whether or not anything supernatural is actually going on is up to you, or you can keep it vague. Have them jump to conclusions, spook them a little bit, keep them on their toes.

Just give them a moment where the absurdity of their current situation (i.e. sitting in the middle of the forest at night trying to interpret whether the lights in the sky are UFOs or northern lights) leads to one of them saying "you realize I wouldn't do this for anyone except you, right" and they can have a Moment.
