Oh yes, Hermione is drinking about it so she doesn't say something unintentionally mean. Like "Please don't co-sign anything or adopt any dogs together". She really worries about his heart but also finances.
It works great! I feel like she'll rely on the PI boys not only to exchange info but also to take her out drinking when she's had a really hard day. She wants to exact change from the inside but the inside is so hard.
