It is funny there relationship always seems tense. He discourages qui-gonn from taking him, then when he takes him (as a favor to the late qui-gonn and a promise) he is weary as was the jedi council of he was. They always present there relationship as tense and scolding or at best it feels indifferent. Original screenplays had more interaction with obi-wan and padme and padme having a deep admiration for obi-wan, thrusting the jealousy of Anakin hate for Obi deeper by the end of ROTS. Obi-wan probably would feel some jealousy in that his master saw much more promise in this boy than him, that Anakin admired Palpatine more than him, and was in love with (forbidden) another politician, Padme. Sadly, so many of the character developments you find in the novelizations and full screenplays are gone. But there are full slapstick moments, poo-doo references, yippees, plenty O' useless CGI for its own sake.
