When to reroll for Obligation?

By progressions, in Star Wars: Edge of the Empire RPG

We started a new campaign a couple of weeks ago, and our second session is this coming week.

We meet on a weeknight and get in around 2 full hours of play after all the table talk is considered.

In our first session, I rolled Obligation and applied the Strain effects--the group's Doctor was worried about the bounty on his head and stressing everyone else out.

In the session itself, for the characters approximately 3 or 4 hours passed. They climbed down a mountain and explored some cave tunnels, having encounters with creatures along the way.

At the end of the session, they discovered an ancient temple within the caves and we ended the session with "to be continued".

Now I'm trying to decide whether to re-roll for Obligation's effects or to carry over the effects of the previous session.

When the sessions are short and don't even cover a full day's time for the PCs, would you roll again and apply the effects anew?

Or wait perhaps until the session after, and consider that in this week's session the group is still stressed from the Doctor's bounty?

In this particular case I'd let it carry over.

Per the rules, I always reroll Obligation at the beginning of each session. Sure, it may have been weighing heavily on the doctor, but his anxiety perhaps passed (especially when confronted by this ancient temple) and someone else's kicks in.

It keeps the same player from suffering an admittedly arbitrary drawback all the time.

Yeah, it up to you as the gm to decide, but officially its every session.

Something some people do is roll at the end of a session, and apply the result to the following session. This way the gm has time to better integrate it into the adventure.

I don't roll obligation. What how can that be you ask!! Because I'm mean,that's why. When the players roll for the Destiny points, the one who's rolls the most dark side gets to roll for the Obligation.

Ha! I like that. I also like rolling at the end of the session, too. Very handy.

So far the way I work it is to roll sometime in between sessions. Our next game is on Wednesday, and as I rolled the other night, I started to think about explaining it to the players.

"So two hours ago you were all really worried about whatever is stressing out the Doctor, but now you've forgotten about that and you're bothered by the Smuggler's problems..."

I think I'm going to treat this week's session as an extension of the previous one because we left the PCs in mid-dungeon-crawl, right about to explore a new room they have discovered. I'd rather keep the Strain effects the same as last time.
