Booth's visit to the Surratt Boarding House after the assassination

[RJNorton]

Can someone explain what the phrase "pray for my intentions" means? It is not a phrase I am familiar with. I was looking at Weichmann's book, and if the timing in Weichmann's book is correct, this reference comes shortly after the "mysterious" 9:00 P.M. visitor departed. Weichmann indicates Mrs. Surratt got very nervous after this visitor departed. At 9:30 I think Smoot found her in a state of feverish excitement and rushed him out the door. Mary then asked Weichmann to pray for her intentions. Is there any way this could be interpreted as her intention to hold on to Booth's stuff for a quick 10:30 pick up? When Weichmann indicated he didn't know what her intentions were she replied to pray for them anyway. She then chased everyone to their rooms. Weichmann says he was asleep when the president was shot. Do we know what Mrs. Surratt was doing at 10:30?
