I don't think they spent much time downstairs. She didn't want to chance them at the table or desk and a roommate coming in and seeing them. I think she ran down and got their food and she just kept him busy so he wouldn't want to go downstairs.
You bring up an excellent observation. The medical examiner stated that Travis Alexander had a small portion of food in his stomach - his stomach contents would match eating only one bowl of oatmeal that day.
I realize that Travis Alexander was getting in shape for Cancun - I assume this means watching his diet.
However, the fact that Travis Alexander ate only one bowl of oatmeal on June 4 has always seemed strange to me.
I'm not sure what happened the day that Arias showed up at Travis Alexander's house on June 4 - but I do wonder if Arias made Travis Alexander her prisoner from the time she showed up at TA's house to the time Arias decided it was time to butcher TA.
On June 4 - Travis Alexander missed an important business call. It was typical for Travis Alexander to miss business calls. A call that I do not think that Travis Alexander would have missed if he was "free" to do what he wanted on June 4.
When Travis Alexander missed the June 4th 7pm business conference call - I wish that one of his friends would have taken notice. After all, his friends report TA stating that if he does not show up (to Sunday dinner) he is probably dead (at the hands of Arias). What if instead of being butchered to death by Arias - TA missed the June 4th phone call because he slipped, fell, hit his head?
I feel so bad for Travis Alexander - I think that he was a good hearted person. I think that the fact that it took 5-6 days for anyone to look for Travis Alexander - shows how Arias was able to "wiggle" her way into TA's life. Perhaps Arias targeted TA because she saw TA as a perfect victim - a person that was lonely, a person that was vulnerable.
For two years there had been a known threat in TA's life. Before TA's death TA had expressed the fact that Arias was going to murder him. When Travis Alexander misses his important business conference call on June 4 at 7pm - not one person made an attempt to find out if TA was okay (especially considering that Arias had behaved as TA's personal boogyman for a long time).
I'm not blaming TA's friends - I'm pointing out the possible reasons that Arias targeted Travis Alexander for her victim.
I do not believe anything Arias says that happened on June 4 - since TA missed a business call (something that TA would not do) on June 4 - and considering Travis Alexander had so little to eat on June 4th - It seems possible that when Arias showed up at Travis Alexander house, Travis Alexander was Arias' prisoner. Travis Alexander was at Arias' mercy - which makes his murder so much worst, IMO. If Travis Alexander was Arias' prisoner on June 4 - Travis Alexander would have been tortured, and, scared for hours before Arias butchered him to death.
