In the Kafe, Robyn helps Katrina out by hitting Birdie over the head with a tray, making the Humans leave. Katrina later on says that Robyn saved her and her grandad's skins.
When talking to her grandad in the Kafe after he makes the suggestion to fire Robyn, Katrina proceeds to say I'm more than her friend. and both Robyn and Katrina hold hands. There is speculation, however, over whether this is meant in a romantic way or not.
