Thank you for taking the time to leave a comment ~
If you're curious about Charlie and Tom, you can always replay the game and spend one session each day with one of them - I put the more interesting things about each patient in the later sessions so only the more commited players will see them - it's how you get on their route, by spending as much time as possible with them without neglecting anyone. But I see why you'd want to treat everyone equally.
Again, consider checking out the rest of their sessions - I won't spoil anything, but you probably won't regret it.
Yes, Dr. Sharpe is a love interest, and so is Elizabeth. I thought it would be nice for a side character like him to be explored a bit more rather than just being a soulless plot device.
