Neutron: Maybe try to communicate in sign language?

Neutron: I could get this objective done if I knew sign language.
RedGiant: Oh, you need sign language?
Neutron: Yeah.
RedGiant: I'm not really conversational in it yet, but I've done a few weeks of it on my PDA!
RedGiant: Let me try! I'm always here to support you through your problems.

Don't you need to have an exposed face for this? Well, you'll get by.
