Maybe something like how they shouldn't throw TIM under the bus without determining his intentions first because he could become a powerful ally.

Which, incidentally, is exactly what Shepard is trying to do: figure out what's going on so they can either work with TIM or not. If Shep finds out TIM is just up to no good, he will insist on being the person who puts a bullet in the guy's head.

Of course, Sheploo's opinion and Jane's opinion on exactly what constitutes as "no good" might be different ;) so we'll have to see how that goes.
