Get out from the sick bay
Talk with doctor Bakatin. Try to get medical file lying next to Milena (on the right), but the doctor says the files are confidential. Try to leave - the doctor says that Milena must rest. Look at the sink on the left, then talk with Bakatin again. Ask him about water, when he turns back to Milena, look at medical file. After another conversation, try to exit the sick bay. When the doctor once again turns back to you, throw a tweezers (taken from the drawer in Milena's quarter) at him. Leave the place and go to your quarter. Try to exit, you will hear knocking.
After dialogue with doctor (he will get Milena a medicine) and first officer, go to sailors quarters. Look at the books on the left bottom capsule, take a key card.
Leave the place and go to sick bay. Doctor is not here, so take a wound powder (on the right, next to the Gerasimov) and a scalpel lying next to the stethoscope on the table on the left.
