Ramayana 2.8.29

भरतस्याप्यनुवशश्शत्रुघ्नोऽपि समं गतः।लक्ष्मणो हि यथा रामं तथाऽसौ भरतं गतः।।2.8.29।।

bharatasya apy anuvaśaḥ śatrughno ’pi samaṃ gataḥ | lakṣmaṇo hi yathā rāmaṃ tathā ’sau bharataṃ gataḥ ||2.8.29||

And Śatrughna too, obedient to Bharata, has gone along with him. Just as Lakṣmaṇa stands by Rāma, so does Śatrughna stand by Bharata.
