Final answer:
Suzie implies that Jake, Stevie, and David should discuss their relationship by initiating and facilitating dialogue, highlighting the importance of communication.
Step-by-step explanation:
In the scenario provided, it appears that Suzie is the one who implies that Jake, Stevie, and David should talk out their relationship. The evidence comes from the context where Suzie stops the other two and engages in a dialogue about Alec's day, which then leads to a revelation about a job. Following this, we see Jack and Suzie looking at each other stunned, signifying that a significant moment has occurred where communication is essential. Therefore, Suzie, by prompting discussion and creating a safe space for sharing, suggests that addressing and verbalizing concerns or news is important among the friends.
