She's quick to think about all the cells they've opened and all the people that they're bringing with them currently.  Right now she knows about half, including the main group and Mindjack will fit on Dr. Destruction's ship, so she turns to the crowd and shouts out to them. "Alright! Half of you will go with May through the sewers," She looks to May to see if she's willing to guide, if not then she'll amend it to, "Or you can go to the sewers by yourselves and split up the Fins will be less likely to find you if we all split up.  The ones we choose will come with us on the ship." She looks to Frenzy for a moment, how're they going to decide which ones to take with them?  She can pick them out in about five seconds or less, she just needs to know which to bring with them.  Hell with any luck they'll split off themselves and therefore they (she, Frenzy, and company) won't have to figure it out.
