There is still nothing. The drone seems undamaged but unaware. Lisa feels a tickle in her throat and coughs.
Up ahead, Bolt approaches the lifeless skeleton. Crouching down, he finds a note with block printing. It might be hard to read, but the flame in his hand grows brighter and brighter as he reads, eventually causing concern.
Here Lies Bug
Squashed Like a Bug
Left for Dead
In his suit of red
This can be his pyre
As you die in a fire
Flammable gas
Will choke your ass
You'll all perish
And the computer I'll cherish
Bolt quickly figures out that the flammable gas mentioned in the note is why his flame continues to grow brighter and why Lisa is starting to cough in the hallway. He also notes that the skeleton is a plastic Halloween decoration and is starting to melt in a creepy way. (Have you seen Raiders of the Lost Ark?)
