the first doctor is like a little kid; he tries to do things his way and his concerns are very self-oriented, and he gets what he wants (or tries to) by tricks. barbara and ian treat him like an old man, but not as an elder- they treat him like an inferior, and sometimes when he goes too far they tell him off, the way you would a little kid. it’s where we see the beginnings of the part of himself that the older doctors (ten and eleven, mainly) despise so much- the part that manipulates people into becoming soldiers and fighting for him. he looks very old, but he’s really very young, and he’s silly and inexperienced and trying to learn all he can while appearing to already know everything. he is very stubborn and intently curious, and hates being proven wrong. though he acts like he does, he really doesn’t know what he’s doing, and that’s what makes him so fresh behind his old appearance.
