Are there any key allies Bryan meets in the movie?

Main Allies

1. Maxine (Kali Reis) — an officer/security figure who helps Bryan during the outbreak and assists him in getting toward the hospital. 2. Carl (Paul Walter Hauser) — a scientist tied to Umbrella Corporation who reveals critical information about Bryan’s delivery and its role in developing an antidote.

These two are the most significant helpers; they understand the severity of the outbreak and provide both physical and informational support to Bryan. Other characters show up briefly or have ambiguous loyalties, but Maxine and Carl are his primary allies.

Sources: multiple movie reviews and breakdowns specify Carl and Maxine as the only original characters (outside Bryan) who significantly aid him during the chaos.
