Regarding the bachur that Horav Miller said should light by his Friday night host, where should he light Motzoei Shabbos if staying in the dorm of the yeshiva he is visiting? (See question 3992) If travelling back on Motzoei Shabbos, should he delay lighting and eating Melava Malka until he gets back which may be quite late?

If he reaches home at the time that there are still people travelling in the streets, he may light himself there with a brocho. If it may be too late, he should contact his parents at home and ask them to lite also for him and in his name as his agents.
