We’ve seen a Leo visit and a Mikey visit; can we see a Raph visit?
They bring him stuff all the time! When he's able to, he'll request certain things or tools from them or ask them to do research to him. Which can sometimes be, like... a lot.

Which is so much better than when he's confused and upset and doesn't understand what's going on...
