Dealing With Mapinguari and Dogged Engineers

As Shakespeare once said, the course of true love never did run smooth.
Since parting with Adrien after their first case, Hugh Quartermain has committed himself to one fact: he wants Adrien. With the months' long trip to Brazil ahead of them, Hugh should have no problem confessing, right?
The problem is the universe seems determined to thwart Hugh. Between creatures terrorizing his worksite, bothersome Americans, and not having any alone time with Adrien, Hugh's foiled at every turn. When Hugh does get Adrien one-on-one, his advances always hit the wall Adrien refuses to lower, but the rare flare of desire in Adrien's gaze motivates him to keep trying.
Come hell or highwater, Hugh will confess to Adrien. He just has to figure out how first.
