I disagree with senator TWFanatic on one point; we should not gather our forces in Arpi. We would be trapped within its walls if Pyrrhus decides to siege it.
However, there are a lot of rolling hills south of Arpi where we could wait for his army. It would serve a double purpose; if Pyrrhus is enticed to attack us, we could fight on the higher ground and rain death upon his phalanxes before the clash. If he decides to siege Arpi, our legion would still have the choice to relieve the city, or directly aim for his base in the south.
That way, all options are open to us.
I agree with the appointement of Lvcivs Cornelivs Scipio as consul though.

Now, over the fate of the tarentine population, I believe its fate rests on the state of our war chest. If it is empty, then we should fill it back at their expense.
Still, there is in the city a large number of skilled craftmen; though they are greek, it would be a shame to waste their skill. We could put it to good use in our own cities by putting them into slavery.
I am strongly against a simple occupation, Roma suffered much from them in the past and showing mercy to them would send the wrong kind of message.
We have to show the greeks that we mean business; Southern Italy should be turned to roman ways as fast as possible.
