Yes, he does. Look at the second pic I posted. It has a shot of planet Earth. I tried to capture it with the UFO in the picture, but the screen was going a little fast. That was actually an alternate scenario for the mission I played. Here's what Marcus says to Indy when you go into his little office in the game for this particular mission: " I'm exhausted, Indy...all these rumors of strange doings out there in the jungle have my head spinning. And our crew is spooked; they refuse to report to the dig site. You've got to get to the bottom of this, Indy! The success of our expedition is in jeopardy! Now take this (whatever item Marcus gives you in the beginning) and leave me alone, I'm a nervous wreck..."
The other scenario the game designers built into this one was that Indy finds the head of See Threepio!! In the inventory it's called a "Strange Idol", and Indy makes a strange comment about it, and when you bring it back to Marcus he says something to Indy like it is a big joke and a hoax, and that it looks like the head of the robot from the movie Metropolis! Hehe.
I wanted to just edit my above post, but oh well. Here's a pic of the alternate scenario when Indy finds Threepio's head. I had to play the scenario NUMEROUS times to get this, because the game randomizes this mission a lot. So, here is what Indy said, copied and pasted, except for the last part; and what Marcus says in the panel below it:
