Catrina was still doing her laps by the time the sirens happened, she had been running constantly since Jilian showed up and dropped her bombshell, she didn't want to make it appear like she knew anything of it so she tried to get to the suit as soon as possible, thankfully her Dom was still being repaired so she would not be able to sortie after Jilian. Instead she decided that it would be best to go look after Lucille, considering the last time she likely heard the sirens was when she was in the spacecraft. As she walked into the room Lucille was still asleep so she just sat down and watched over her.
