Alright, uniformed guard... Great...
That makes things harder for sure. Helen ponders how to get past that obstacle. They could attack him, sure, but that would be pretty hit and miss. They could sneak around and see if there is a way past him or try to make the guy let them through without asking too many questions. Looking how close they've already come, she sees few options. So she doesn't ask what Al and Raul are communicating by passing messages, but walks further towards the gate where the guard is.
OOC: Plan is to get inside the building and see if we can find the place where the mark lives, preferrably without her currently being in. If that doesn't work, getting some details to the picture would be a start.
