18. D: Don't be sad, OP. The Doctor doesn't seem very prone to hating people for their inadequacies. Think the reason you feel you couldn't handle an adventure is coz you've not been on one yet. You can't be ready for something like that; it's the kind of thing that changes you when you're in it, right?

And besides, emotional support seems like more the thing the Doctor would need anyways. Unless you're so completely incapable that you go and get yourself killed. Coz that would be totally not emotionally supportive at all.

ANYWAYS--don't be so down on yourself. D: I bet you'd make a fantastic companion.
