What would your Ryder do?

I think we have done everything there is to do in ME:A by now and since there likely isn't going to be any new material for us to think about, I wanted to set a thinking challenge: What would your Ryder do if (s)he mysteriously found themselves back in SAM-node in the past right after Alec's death without any idea how they got there? How would all the future knowledge change their journey and what would they try to accomplish first? Would they tell everyone that they have time traveled or try to go on business-as-usual? When would they go to Meridian?
