I'll use the same bay numbers the game uses. As you enter the area, bay 1 is the first one on your right (where you hid from Ewan), and bay 2 is the next one on the right. Ewan is in bay 3, the one with the thermostat, and bay 4 is the other one on the left. That is --
p- _____
Bay 3 | | Bay 2
| |
Bay 4 | | Bay 1
p+Got it? Okay, here we go:
Forbes, red -- bay 2, left wall, upper right bank
Cameron, green -- bay 4, right wall, lower right bank
Hay, blue -- bay 2, left wall, lower left bank
Murray, yellow -- bay 1, left wall, lower left bank
Douglas, purple -- bay 4, left wall, lower right bank
