"I can fetch you some pictures if you like," says Gulati, but she doesn't move as Yaktal calls up the security footage on the monitors.
"The concert started at... well, call it 8pm Earth Standard, to save you dealing with Abbai time measurements. Here's the main hall, outside the auditorium..." She spools through some footage.
"Look, that's her," says Gulati. The image, when soomed, shows an Abbai female slightly shorter and broader than average. She is accompanied with a group of other Abbai females, one of which has a distinctively large and red head crest.
"So, if we have a look around 10:30pm EST..." says Yaktal. Again, she spools through footage. "Hmm.... Look at that...."
The footage shows that Mriva, her red-crested friend and two others are not leaving by the main exit, but heading off down another corridor.
Yaktal enters some more parameters.
Then Mriva and her friends travels down several corridors. They look a little shifty, and pull up the hoods of their gowns over their heads. The footage follows them through the university, right towards Sushar's lab. The last bit of footage is the doctored section. The figures that briefly flickered in the corner would seem to be Mriva and friends entering just before the camera footage is altered.
Gulati lets out her breath explosively.
