The Tails That Bond Episode 3: Trust (Sonic SFM)

Links to the composer's channel: It's the morning after Sonic and Tails met, and Sonic has made the decision for the two to be brothers. But to make such a change is not as simple as that, as Tails still suffers heavily from the trauma of the past few months of his life. For Tails to truly be at home, Sonic will have to do all he can to maintain Tails' fragile sense of trust, and the trust of both will be put to the test.
